Fuelly Forums - Trouble syncing from GC to Fuelly

I'm trying to sync from GC Free to Fuelly. I can no longer even get to the main screen on GC--the splash page informs me to "Sync my data with Fuelly", "Download Fuelly", or "Export Data". I've exported the data and sent it to myself in an email, but apparently there's nothing I can do with it--saw on another forum post that there's no import capability within Fuelly. I've downloaded Fuelly, set up an account, attempted to sync my GC data (no error message appears telling me it didn't sync), tried syncing in Fuelly (again, no error message)--and nothing. No entries exist in my Fuelly app. I don't see how I'm supposed to migrate my data from GC to Fuelly. My sync data appears to be getting lost somewhere in cyberspace. I read through an earlier thread from last September, and they all seem to presuppose that one can get into the GC app and/or some data was migrated into Fuelly, just not all of it. I can't get ANY of it to sync! Any suggestions would be helpful. I've used GC since 2010 and would hate to lose all of my historical data. Thanks!
