Hi Paul,

Not sure if this is any help at all, but I had terrible trouble trying to autiguide usually getting the same message as you.

Can't swear to it, but my problems suddenly disappeared and all works fine now - I'd been playing around with so many things I can't be certain - but:

In CCDSoft, on the autoguide Tab, there is a setting "Reverse X". How is that set for you? For me, clearing it is I think responsible for solving all my issues.

Worth giving it a go - setting or clearing it.

You never know, it may help....
