I have been using Sugar Pro (On Demand) for about 3 weeks. For the first week or so I was able to attach documents to notes and the knowledge-base. Something changed on my PC and now I cannot upload anything. The system just spins for a long time and then times out. I get no error messages. I have contacted Sugar tech support and they were unable to figure out the problem. It is local to my PC. I have tried on other PCs both inside and outside of the same network. I have Microsoft Security Essentials and I turned off real time protection.

Any suggestions would be greatly appreciated to help me pinpoint the problem.
