Index was out of range (1 Viewer)

[AllenConquest]

I'm running the TV server on a dedicated XP HTPC box and the client on a Vista machine. I just updated to a new SVN (but same problem was happening on an old one as well). After watching live TV for a few seconds the client MP crashes. The error log is attached and shows:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

I'd appreciate some help. What other information would be needed to help debug this problem ?

Thanks,

Allen
