CRC could not open file: Permission denied

It can be either HTTP server sync error, or that somehow your pc thinks that the server has been modified but not refreshed/updated with the modifications. Have you tried erasing GTA and MTA and downloading them both. It has nothing to do with what drive you put it on, because they're not windows permissions. But try installing MTA on C drive after you completely removed it (dont keep settings or anything and restart your pc) maybe?
