This is a real odd one and if anyone can help, it would be greatly appreciated. I have for since day 1 been running an MGE Eclipse 800 UPS under Windows XP Pro. Then, out of the blue the UPS service has stopped working with the following error: A system error has occured. The UPS Service is not configured correctly. Now, I'm not sure if a file is missing or damaged but it's not the UPS or the UPS software as I've tried both on another machine. Somehow (somewhere) this service has gone pear shaped and I haven't a clue how to fix it. A system restore doesn't work and I flatly refuse to format, just to get it working. Any help or ideas? Thanks.
