Spark died on my Win7 x64 install

I’m the sysadmin so this looks pretty bad. I had a problem with Spark, couldn’t get it to run, so I removed it completely, re-booted and re-installed (several times). Spark will run and I can log in, but I can’t send any messages. When I try it only sends my user name, not the message. I can log in on other workstations as myself and everything works normally. Any ideas?

Thanks,

Marc

Is UAC enabled?

No, UAC is disabled.

I am having the same problem. I am also a sysadmin. Has anyone found the solution?
