well that didn't work.
13% was actually as far as it got and has been stuck on 13% since my last reply.
so i quit the program, waited for the sync icon to disappear, and then launched the program again, but it's just back to how it was before - not syncing at all.
When I first got the app, I found that I had to do this cycle many times before I got the complete block chain. While it looks like it hasn't moved off 13% for you, its actually got 13% more than the last time. So each time, the number of missing blocks is shrinking. Another thing you could try is to add a peer (the fallback nodes) manually and then restart the software. Older versions of the desktop clients can disconnect which I think disrupts the mobile wallet sync. By restarting or specifically connecting to a peer on a current version, you help yourself out.
