just updated to Windows 10. With the update the email failed to initialize in Oper a12.18 (browser and mail client sitll integrated). I keep getting the notice :
Error While initializing Opera Mail.
There was a problem initializing Opera Mail.
The following file appears to be in use by another application: C:\username\Appdata\Local\Opera\Opear\mail\omailbase.dat
To retry please close the application that uses that file or restart your system.
Restart of the prog or the system doesn't do anything,, I ran the ccleaner regitry tool but it didn't help either. When I ran the system in safe mode (network) the mail appeared, but didn't work (fetching new emails, or sending).
The email base is pretty big, and would be a pain to not be able to use it as I did for the last 10 years.
Any help would be appreciated!
