Converter error (vBulletin 3.8 to SMF 2 RC2)

[marazmus]

Hello.

1. Installed vBulletin 3.8, SMF 2 RC2.

2. Converting works fine up to this stage:

Converting posts (this may take some time)...
Successful.
Converting polls...Wrong value type sent to the database. Integer expected. (expire_time)

and stops here. No "Continue" button, no links.

What may be wrong here? Can anyone explain this problem?

Thank you.

p.s. Converter last URL was convert.php?step=1&substep=9&start=135600

Solved (poll tables was corrupted). Converter works perfectly.
