Mac Desktop Manager Won't Connect

I've been using Mac Desktop Manager (1.02 the latest version) and it's been working fine, really easy backups and all.
The problem is that for some reason today, it won't recognize when I connect my blackberry (8700r, 4.5). I tried the cable on another computer and it works fine, tried a reboot but it still won't recognize the blackberry and I need to reinstall my contact.

Any ideas what to do here?

Maybe use an older version? Might help.

But it was working fine, this is the first time this happened. Has anyone else noticed this?

Mine had been working fine, but now the Desktop Manager won't recognize my Tour.
