DB Error: Duplicate entry for key 'sessions_pkey'

[agcorneliu]

hello, and tell you briefly my problem: I had installed on a server (older - OpenSuse 11.4) OJS version 2.6 which worked perfectly.
I recently made ​​updates to the server (OpenSuse 12.1 - x64) and I wanted to reinstall OJS - the same that worked on the old severe. Backup worked but when I use it gives me an error like << DB Error: Duplicate entry 'om0jqkcplsgfd7uogguq0l3u3k5lghmdeq3ndinr' for key 'sessions_pkey' >>
Moreover, we can say that OJS installation works, but it does not work any new and clean version with the same error like OJS << DB Error: Duplicate entry 'om0jqkcplsgfd7uogguq0l3u3k5lghmdeq3ndinr' for key 'sessions_pkey' >>
Site we found at http:www.analegeo.uaic.ro, thanked you expect an answer as quickly as possible. I can say I'm the one responsible for installing the server and the OJS.
I tried about all the variations on this site, give me a solution please ...
with thanks,
