I'm running the 64 bit version of Windows 8. I'm having a critical error running the client in server mode. I was able to run the client initially to update it, but when I started it in server mode it bombs on the Gridcoin Mining Module. I then get a "Gridcoin-qt has stopped working".

I have the 64 bit version of Boinc (7.2.33), but the Gridcoin client is not attached. The contents of my gridcoin.conf un my Roaming/Gridcoin directory is below.
server=1
rpcuser=myusername
rpcpassword=mypassword
rpcallowip=127.0.0.1
rpcport=9332
Is there anything else I can try?
