Just checked Garmin website and they now have taken version 7.18.0.0 away and went back to version 7.17.3.0.0. If something is wrong with 7.18.0.0 hope they put a new version out as I have 7.18.0.0 installed on my computer.
Express 7.18.0 deletes all activities
Dunno about that but at least they've fixed the problem when adding new equipment "unable to contact server"...
Yep - just reloaded V7.17.3 on Windows 7 Pro & all working fine now.
