"Unable to access the MusicBee library path : C:\...\Music\MusicBee"

[pretentious_moi]

No longer able to open MusicBee because this error keeps popping up. I haven't moved the folder or anything. My friend has had the same problem this week so I thought this might be a bug with the latest version of MusicBee. Version 2.5.something, Windows 10. All help appreciated.

Can you copy/paste the lines from the error log from about the time you launched MB and got the error?
The log is called ErrorLog.dat and it is located in the AppData folder under the folder where MB is installed.  Don't worry about the .dat extension.  It's a plain text file.  Please don't paste the entire log.  Just the most recent launch error.
