[...] then retry to import your old profile saved as *.BAK: rename it to *.dat and launch Miranda again
Thanks for help.
Not quite sure if I follow correctly:
After installation of all libs from Core (done), I go to my profiles folder. This is how it looks like:
AvatarCache
Avatars
Logs
MirOTR
tabSRMM
amix@DESKTOP.dat
amix@DESKTOP.dat.bak
amix@DESKTOP.dat-lck
I then did:
1. delete *.dat
2. rename *.bak to *.dat
3. start Miranda-NG and let it convert the profile
I just did that. I got a lot of dialogs with "Order Number xyz not found in (several plugins, like ICQ, IRC, Steam, Facebook, etc.)" After that, Miranda started, but no contacts were available in my contacts-list. Only the folders/groups I had. Now the profile is 512KB, before it was 18.816KB. Also, it seems, that none of the plugins I have got loaded.
When I start out with a new profile, I get the choice between:
dbx mmap and MDBX drivers. Which one shall I take? Also, if I select "Start in service mode with import.dll" I can not continue, just quit.
I then decided to delete all from Miranda NG folder and copy all from the archive you suggested into it. Sort of a fresh install. I also did delete the whole profile folder. But then, upon profile creation, chosing the MDBX driver, I got a dialog: Error 1. And a second dialog: No suitable database driver found.
This is what I have now (Windows pops up warning me, that the application would be unsigned/insecure, which it did not do before):
