a followup..

a reinstall and replacing just a basic files did the job (mail, bookmarks, contacts, wand etc..) as far as I could tell the problem was caused by a file from User CSS directory, eg: C:\Users\YOURUSERNAME\AppData\Roaming\Opera\Opera x64\styles\user
couldn't tell which one though..

thanks for your help, much appreciated!!
take care

hey guys, thanks for the input!!

• unfortunately i havent reinstalled the Opera yet as it took forever to backum the latest files (more than a decade of emails), so I had to postpone it for some other time (today if possible)
• trying the unlocker thingy on omailbase.dat, resulted in the same notification as before (Dave, great app, I tried to find sth like it but couldn't)
• removing the omailbase.dat from the folder, resulted in the same notification

I guess the most probable option is that the file has been damged,.. ?

...anybody?

HEy there,.
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!

Thanx

@herrpietrus: I'm using it as a browser, mail, feed agent prog so 20 is not that good of an option

@leocg: thanks for the link,.. it did the thing, it's working :), you really helped me with this :)!

I have had problems with this previously, when Hotmail didn't want to show in Opera (as some other sites didn't) but a restart usually helped

I made a clean Opera install (12.17) recently and here I can't seem to get hotmail to work,.. I get the login page and can login, hotmail starts to load but ends up with a white window. It works flawlessly in eg Chrome.
any suggestions what might be the cause?
