Mobhack Operation Error

[mkr8683]

Every so often, when I'm using Moback, I get the following error:

"Access violation at address 00401EB9 in module 'MobhackWW2.exe'.
Read of address FFFFFFFF."

I can continue working, but the message pops up every time I try to save the OB I'm working on. When I close the program, the first error message is repeated, then this pops up after it -

"Access violation at address 00401EB9 in module 'MobhackWW2.exe'.
Invalid pointer operation."

Closing Mobhack and restarting it works, but now I have to save every time I hit F12 because I don't know when I'll get the error. Are there any known fixes to this problem?

Thanks,
Matt
