We try to fix all bugs reported in a timely matter. This one will be included along with any others reported in a free update.
Technically it is a CS5 bug that a call to get the number of sites returns a very large number when in fact it should return zero when no sites are defined. We will produce a fix to work around this CS5 bug soon... as you can see it was reported about a week ago and we just found the problem 4 days ago, 2 of which were a weekend.
In the meantime we are giving the work around to set up a test server, even a fake one, in your site settings and it will then properly update your site settings to the cs5 format that doesn't cause this issue.
Did this help? Tips are appreciated...
