I have a laptop which contects to the office and home and is used with a VPN.  It has Spices.Net Decompiler.  It was previously activated, and I have used it a number of times in the past.  Today I'm being told I need to reactivate.  Why?

Also, Since at work I'm behind a proxy, I cannot Activate because there doesn't appear to be a way to configure a proxy.  Am I missing something?
