o.k., I looked into the code of your script.
In "import.php" I see in the second half this code. I guess this is where I have to add something to reflect the PP usergroups and their IDs. So over the next 2 hours I will do the following:
1. I will add some lines in the code of the import script below (the part I marked in bold is according the UG-ID numbers I posted earlier in this thread).
2. I will then again make a fresh install, create additional usergroups within vb
(to have something to import to for the code addition in bold), check again their UG-ID and put the numbers accordingly in the lines in bold below.
3. Then I start the importscript.

Theoretically, the UG-ID-Problem should then be solved, or do I oversee here something?
