deleted all my settings, actions etc & re-set all columns
Could you check...
the folder %appdata%\mp3tag
and see if your old user settings are there?
And/or check the previous installation folder and look for the same thing.
Have you changed the installation type from portable to standard or vice versa?
%appdata%\mp3tag is folder that items were deleted from. was 63 items now the 2 basic.
No change from type just like always install new version on top of old, no portable no change last 8 years no problem till now.
there is no previous folder as it installs on top of old version
also columns were all re-set
this is first version that did this.
win7 ultimate (64 bit) 8 gigs ram. no updates ever.
Hope you had a backup of your settings. I've just did a code review on this issue and could not find any situation which would delete your configuration when simply updating.
Can you somehow reproduce this?
