No idea,it's strange.API is drawing by programming.

I get the same message... when I'm not connected to the internet.

It could be that GooTool is being blocked by the Windows firewall or some other firewall software.

I'm using ZoneAlarm. Gootool has full internet rights. The profile backup and publish are working OK (suggests not firewall connection problem?).

For the record.
Bypassed the problem by downloading and installing a newer version of Gootool 1.0.2.376. This works as it should right from the start.

Now I've roughly 15 updated versions to work through!

I missed this post for some reason. If it happens again, post the relevant logfile section so I can diagnose it.

It's started to do it again!
