[solved] Other problem ERROR UNKOWN

I think the main error for dont show my sessions is here.

Hello,

the problem is on your database. An important file is KO (hands_summaries_v2...).
You probably had a crash of your PC and the database is now KO.

You can try "Start > Repair the database".

Or you can restore your last backup and make an import of all yours archives (Import > the last item).

You can also make another installation over it without keep data and config.

Verry sorry for this.
