We were running Omega 2.6 with our CE-5000 plotter with no issues on our old XP system then our computer crashed. Purchased new 64 bit computer with Vista and re-loaded Omega then had to wait for Graphtec drivers. Just loaded the 64 bit drivers and we are getting a communication error "Cannot open USB: For Spooling~tmpa13F.tmp. We aren't a production facility so time isn't too critical but we'd like to get some necessary work done.Any help?
