I run AC in a 2003 windows server environment. The server is not used as a client and most of the time no one logs into it or runs AC in it except me. Ever since I updated to 6.010 I have noticed that when I start AC in one of the clients, a windows pops up that states the message above. Also, amazing charts does not backup automatically as it did before. Sometimes days go by without a backup until I notice the error. I have set up ac to send me an message after each backup but I still manage to overlook this anyways... Any way to fix this? Once I start AC in the main computer the problem goes away until the server has to be restarted (often due to automatic updates) and then I have to manually restart the program or the error message recurs. I did not have to do this before. Sounds to me that the ac backup service is not restarting automatically, which I think it should. Any thoughts?
