Garmin express not synching my 910XT after upgrade to 5.5

After the Garmin Express upgrade to 5.5 version my 910XT not synching getting error message.
The problem is that the upgrade broke the ANT driver here is the Garmin Express log. The Garmin developers need to look into it.
One option is to uninstall 5.5 version and rollback to a previous version that does not break the ANT device..
Can't believe that Garmin does not do a QA when they did this upgrade...:mad:
