I'm upgrading from Telligent 6 to Telligent 7, following the instructions posted here: http://telligent.com/support/telligent_evolution_platform/community/w/community7/24675.how-to-upgrade-telligent-community.aspx#Upgrading_from_6_x_to_7_0.
I exported my widgets, creating files named EditedWidgetsBackup.xml, AllWidgetsBackup.xml, and SiteThemeConfigurationBackup.xml.
However, the instructions give no information on importing these into my Telligent 7 system. I assume I use Import Widgets from Manage Widgets in Site Administration. But when I do that, browsing to those three backup files, I don't get any indication of success. Should this import have restored my widgets (one of which is a plug-in "GeoFluent translation" widget)? (Sorry, I probably haven't given enough information here.)
Something is amiss in my upgrade, probably a CSS issue, because I'm missing the text and outlines for many tabs in Site Administration, and can only access the Widget Studio tab because I remember where it should be, and put my cursor at that spot and get the studio tabs when I click there.

Am I missing a resources file that paints those tabs and their labels?
Thanks,
- Willie
