I'm not sure what decompressed files you deleted; you aren't supposed to delete any, but perhaps you meant compressed? :) The original compressed file (XComGame.upk) should be renamed or moved out of \XCom-Enemy-Unknown\XComGame\CookedPCConsole The decompressed XComGame.upk file should then be placed in \XCom-Enemy-Unknown\XComGame\CookedPCConsole No other .upk files should be deleted/renamed/moved for that version of the mod to work. If XSHAPE doesn't give any error codes, then it might not be the cause of the problem. XSHAPE should say: xcomgame.upk SHA hash updated. 1 SHA hash(es) updated. Yep I deleted too many files. Later I just renamed one compressed file and was fine.
