XF 2.1 Lost members after import

[knobby]

Hi Folks,
Just installed XF2 and imported the data from my other MyBB forum. Everything appeared to go well with no errors shown. My old forum has 1067 members but after importing the data into XF2 I have 660 members.
Any idea where the 401 members disappeared to and how I can get them back?
Thanks

Cancel that - I've found the problem (it was with my old forum)
