Indicator:
If you try to unlock with "UnLock MapSource.exe" it hangs at these files.
At first I thought it is something wrong with my hard drive so I deleted torrent and re-downloaded it at different drive - the same result!
My solution:
I downloaded 7 "rar" files from first post (3,31 GB) and everything went OK. Replacing 4 files from this DL to magnet "big" one - proved I was right. Now "UnLock MapSource.exe"
works in both versions.
