Underfoot client Problem with 1 account

[Riklin]

Mostly after you select a server (any server, not just my own), then it errors out about 1/6 of the way through the progress bar. The error it gives is:

The instruction at 0x76f08dc9 referenced memory at 0x00000014. The memory could not be written.

When the error screen is closed, it crashes the game to desktop. Again, this only happens when trying to load this one account in underfoot on any of my 3 computers (2 with windows 7 64 and 1 xp 32.

Thanks again,
Rick
