Error message while importing hands

[mashpot]

I keep getting these error messages:

2011/09/15 09:27:32: PokerStars: Hand Imported (#67520631527) from Pilcher V
2011/09/15 09:27:34: Access violation (1) (Flags: 0; Address: 0x0060169b; EIP: 0x0060169B)(Line #33)

Doesn't seem to be affecting performance. But just started happening recently and I didn't change anything.
