Multi Theft Auto.exe - No Disk

[Backsage]

Hello, guys. I need some help here! When I tried starting MTA 1.4 on my computer, I get this error message:

"There is no disk in the drive. Please insert a disk into drive \Device\Hardisk7\DR7."

Any idea on how to fix it?

Please download and run MTADiag and follow the instructions. If MTADiag doesn't launch, please install Visual C++ 2012 runtimes (download and install vcredist_x86.exe) and try again.

Press 'n' when asked.

Post any Pastebin URL MTADiag gives you.

Edit: I just changed the drive letter and now it works. Don't think it's necessary, but thanks for trying to help.
