hello, my game used to work perfectly until a few days ago, i tryed to open my game via Steam and i'm getting a CMD message saying '' Program is too big to fit in memory '' .

Sounds like you are using up all of you're RAM. Look around on the internet there are many guides on how to free up RAM space.

You can get a free tool called game booster which will free up some RAM.

still doesn't work :\ everything is closed cept game booster and steam, using almost no RAM and when i start the game i still get that CMD windows telling me that the program is too big to fir in memory :\

Can you list your specs please?

it says that i have 2GB Ram, i though i had 4.. maybe one of my Ram card burnt or whatever, could it be possible?

Sounds like the main exe got somehow corrupted, download a fresh one by checking the files integrity.

Yeah it is possible that the RAM stick(s) could have broken. If you know how to take out the RAM it should say on the RAM it's self what MB/GB it is.

If that'd happened the system wouldn't boot and you'd be getting a bios error stating its detected a dead/damaged stick, unless someone actually pulled out some of the sticks. Fraid your system only has 2GB after all, which is enough to run the game still. You didn't do something weird like disable your page file though eh? (You'd have to very purposely do that so no worries if you don't know what that is, but if you did that's a really bad move especially with only that much ram)

Before I upgraded my computer I only had 2gig of RAM. One day I noticed I only had 1.5gig ?! I had 4x512MB and one of the RAM sticks had stopped working. Don't know how long it was like this as I didn't notice it right away. The computer was working just fine although a bit slow with less ram. So one of your RAM sticks could have stopped working. RAM's cheep just buy more.

First download CPU-Z and check in the Memory and "SPD" tab for what's in your RAM slots.

Right-click on "Computer" in the start menu and go to Properties. If you see something like Total Ram: 4GB (1.99 Usable) then indeed you have a RAM problem.

If you're using Windows 7 you can open up "resmon" using the Run dialog box, go to the Memory tab, and look at the Memory usage graph, specifically "Hardware Reserved". If Windows detects you have RAM in those slots but it can't use it, it'll show up under "Hardware Reserved".

Example: When reseating my huge CPU cooler I had to take out two of my memory sticks which are exactly the same make & model except for one being a newer revision, and accidentially swapped them when I installed them back in. This caused 4GB of RAM to disappear (Windows saying it's "Hardware Reserved"). Swapped them back so that the newer revision sticks were all in the same channel (like I had before) and it worked fine again, all 12GB usable.
