Sync error

Sync works well with my computers. However, when I put the computer to standby or resting state or switch it off  and restart the system again the next, I receive a message that Endnote could not connect to the server. Which is no surprise, because I turned the computer off. I have to click OK on the error message every day, which gets kind of boring, and if I don’t do it, Endnote does not sync in the background.

Is there a possibility to switch this off? If not, will the problem be solved in future versions?

Windows 7

Endnote 7.3
