SNG Tracker Poker Tracker Import Failed!

[pitchx]

I have been using SNGTracker for over 900's SNG's without problems, quite happily importing my data from PokerTracker.
Last week I started getting an error message when trying to import <font color="blue"> </font> "PokerTracker import failed - Object cannot be cast from DBNull to other types." <font color="black"> </font>

I have tried reinstalling, clearing filters and compacting my PokerTracker DB all to no avail. Within Pokertracker the data seems fine it is only when I try to export I get the error. Is there anything obvious I am missing or a solution to this problem that anybody is aware of? [img]/images/graemlins/confused.gif[/img]
Thanks for reading, I hope someone can help.
