It appears that the web host provider had some serious network problems last night and they've finally been resolved. During this outage, I found a bug in XBF that was causing it to exit (without any indication) whenever it did a version upgrade check due to not being able to contact the server. This, of course, has been corrected and will be included in the next release so this sort of outage will not hinder the usage of XBF for the Desktop.
