This is the leading verified cause. BitDefender's active scanning feature mistakenly flags the file streams used by the ROTTR engine during the decompression process. Instead of quarantining the file (which would trigger a "File Not Found" error), it blocks the read process, causing the game to crash with a "Bigfile" reference.
If none of the above works:
