Problems Importing IPB v2.0.4 into vB 3.6.7PL1

[9clics]

I'm using ImpEx 1.82, and I've got problems importing an IPB v2.0.4 database into a brand new vBulletin database (v3.6.7PL1) :
- Some private messages are not imported (100 pm are not imported)
- No polls are imported (it says array_sum() [function.array_sum]: The argument should be an array in /impex/systems/ipb2/008.php on line 134)

2.0.4 isn't a supported version 2.2.2 is the supported version at this time.
