Jairsl2206: STEPS:
Go to "fsgame.ltx" and open the file with Notepad.
you immediately notice the repeated lines in the file, read as follows:
"$ App_data_root $ = true | false | C: \ Users \ JAIR2 ~ 1 \ DOCUME ~ 1 \ Stalke ~ 1 \

Which will be repeated several times, all you have to do is delete repeated lines.

falloutttt: Hello Stalkers!

I have been playing SOC and COP time to time and dint had any problems till today. when I start the game, it gives an error saying: "the file fsgame.ltx is corrupted (it contains duplicated lines) please reinstall the game or fix the problem manually." I'm not sure what's the problem is. I can always reinstall the game, but was wondering what the problem is. I don't use any mods or anything like that.

Thanks in advance!
