Bug in Tag Inspector - Object not set to an instance of an object

[fred]

Press 'Edit' on a track - press 'Tag Selector' tab - delete REMIXER & MIX ARTIST tags then press 'Save' - error message box displayed with above message. In the Edit window a red exclamation icon appears against the save box with the hover text 'The file(s) have been updated outside MusicBee - you may need to rescan them ...'

[Steven]

do you still have a copy of that file with those fields still active? if yes (or another similar file) can you send me a link to a zip of the file.
Also post the error message at the end of the error log (help/ support/ view error log)

zip file containing error log & music file

[Steven]

This fixes the issue:
https://getmusicbee.com/patches/MusicBee32_Patched.zip
unzip and replace the existing musicbee files

Hi - I have also come across this error. Downloaded latest version and patches above but still occurs. Only seems to impact single track on an album and not every album but then stops editing that track.

[Steven]

can you post the actual error dump

[richg]

Error log below. As additional info I tried deleting the album and ripping again which has worked previously but on this occasion still got the error on a single track.

Thanks

this issue is actually unrelated to the OP. Are your wma files DRM protected by any chance?
If you send me a link to a zip of one of the them then i will have a look at whats going on

Thanks Steven - link below

i have no issues updating and saving that file. The only suggestion i have is to make sure you have the windows media codec pack installed if you are using the windows N series
