Have you tried running Repair/Optimize on the table? admin cp > maintenance > repair/optimize tables > select the forum table > hit repair/optimize. You may have to do this a couple of times.

I have old backup. Realy table 'forum' from backup add to new mysql base?

Did you try what I suggested? Tables crash all the time and usually if you repair them, they are fine.

You cannot add a single forum from an old backup.

There is no column 'excludable' in a default vb table 'forum', so that error is because of an add-on. Try disabling the add-ons and try again.
