Cannot add windows service monitors

I am using the free version of OpManager.

Last week, I set up a server with several windows service monitors, and everything was working properly. Today, OpManager was reporting that every single service it was monitoring was stopped. I checked the server and the services were all running properly. I removed the windows service monitors from the device, and then attempted to add them again. When I click the link to iterate the current service on the device, I receive this error:

Error # Not enough storage is available to complete this operation.

I upgraded from build 6003 to 6005, and am still receiving the same error.

Note that both the OpManager server and the server I am monitoring have at least 20 GB of space on each of their installed drives.

Any ideas?

Thanks,
