Problems after doing backup

[wdebacker]

I copied all my musicfiles on my harddrive to an external USB drive and now Musicbee does not find my libraries

Message I get is:
MusicBee v2.5.5804.26036 (Win10.0), 16 Feb 2018 14:08:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
   

what happened and howw can I solve this?

1. did you copy libraries (.mbl) or music files (.mp3, .m4a, .flac, etc.)?
2. if they were music files, did you copy them by mb computer node or by windows  explorer/any other external file manager?

btw, 'copied' or 'moved'?

You are using a very (very!) old version. I suggest updating to at least 3.1 if not 3.2

just a note: its impossible if host os is xp.

I copied the music files (flac, mp3). They are already sorted in folders by composer or artist
I copied them with windows explorer

you can try 'remap music file paths' command, but cant help you more, maybe someone else can.
