problem with bug fixing need help

[Nat_Crelk]

Ok I'll try to help you finding that Program Data Folder.

1) Go there : Config Panel -> Folders Options -> Second Tab ("Display")
There you can see a scrolling window and at the back there is a little folder icon with two
checking boxes :
"Display hidden folders and files"
"Do not display hidden blabla"

2) Check the first box in order that your computer will now show U the hidden ones
3) Click "Apply" then "OK"
4) Go to C: (or whatever letter, the location of your program files folder) and now you can see the famous and so mysterious "Program Data"

See there if there is no 7.62 old files left.
The folder should be named 1C Comp or 7.62 High Calibre.

If it's not that solution I'm sorry but I don't know what to do otherwise

PS excuse the spelling and grammatical mistakes 'cause I'm french.

Hope that will help

EDIT : try to install the Unofficial Patch. I'm playing with (plus the Blue Sun Mod) and a very lot of issues have been resolved with those ones.
