Like it says on the topic desription, it crashes, without warning, one minute i'm happily clearing out and alien crash site next minute i'm unhappily looking at my desktop, having just lost all my unsaved mission data. The screen flashes black then its as if I had come out of it properly, no error messege or anything. I think it may happne when I click to do something but I'm not too sure. Any one have any idead whats wrong?

Find out the problem, once you find it out post it here. :hmmm: (Well no duh!)
I once had a problem that whenever I told my Avenger to do anything the game would
crash. The bad thing was it was after a ship and whenever it shot it down it would crash.
If I tried to minimize the battle it would crash after about a minute game time. Eventually
I had to sell my Avenger. The strange thing was it still showed the minimized picture
in the corner and if I clicked on it... BOOM my game would crash.

Mind posting your computer specs, just so we can take a look?

windows 98, hard drive= c: 2gb, d: 700mb, ram= 128 ( i think), pentium 3, direct X 6/7?

Did you try turning off hardware acceleration?

nopw, will do next time I remember and will post if prob happens again

I tried it and it only made the games run ridiculosly fast

new thing to add:

I research a floater medic, and when its done the game crashes.

regardless of whether I look at the research or not the game crashes

Sounds like you have a corrupted save game. i'm afraid your SOL

-Blade FireLight

the Floater bit was on a new save game, the crashing for no reason was on a different one.

Diferent as in a fresh game? or just a diferent save slot of the same game?

a fresh game, but in the same save slot

My game crashes when I look at Floater research as well. I was hoping someone knew how to fix this.

Windows XP, 8GB HD, Direct X 8, 256MB RAM, using f0dder patch.

I was just getting into the game too. February of first year, just starting to roll out the laser rifles. Please don't tell me this is going to happen everytime I get to this point in the game.

Same for me. I remember, that something similar happened with the collectors version of TFTD, too. UFO chrashes, when the Floater medic research has been finished. Im not sure at this point, but I could swear that I've never captured this medic. And indeed, the research screen shows me a Snakeman instead of the Floater Medic

Win2k - SP3
AMD Proc
512MB DDR
GeForce3
f0dder Patch

Load the saved game and cancel the medic research. Never try to research it again.

mine crashes to and i dont know why

my specs are 128 ram 6.4 gig hardrive and a pentium 2 400 mhz proccesor
and i have a ati rage pro video card.

My ufo used to crash a lot and without any error messages. Turning on the win xp compatibility mode with all its features (256 colours, no visual theme's, no advanced text services) drastically reduced the number of crashes.

I know there is a bug in the game that makes it crash. It could be your problem. Whenever you save a game and one of your ships is currently tailing a UFO, it has a high probability of crashing. It mostly happens if, say theyre trying to make a base and your still tailing some UFOs while you land on a tactical mission. When you finish the misssion, the game while go to the global view, zoom all the way out, and go back to windows. Just make sure you dont have any ships tailing UFOs when you save or go on a tactical mission; thats the saftest way to avoid that problem.
As for the researching floater medics, Ive never had any problems with that on either the original or Collector's Edition
