I have tried to solve the "severe network problems" issue forever. I've uninstalled, deleted everything, reinstalled.
You have had the most recent version installed? The 'network problems' warning maybe a gui glitch also .. you can verify the 'real process' in the advanced settings menu by typing "info".
I have used both 0.92 and 0.93c. I don't know if it's my computer being old (it uses DDR2 RAM, but it's 8 GB) or what, but Bitshares has problems syncing and it always crashes when I try to quit. It didn't always have problem syncing though, and older versions (pre 0.92) worked just fine. I was able to sync and send transactions.
Anyway, I managed to import the keys to graphene, but none of my BTS are there. No balance.. should be 49k. Is that normal?
It kind of depends what balance you had at the SNAPSHOT time .. which is why you should sync the old blockchain first to be absolutely sure about your balance ..
Have you ever done anything with your balance?
By SNAPSHOT you mean the balance at the time of my latest backup/export? If so, the balance at that time was 49,999 BTS. The balance at the time of the first release of Bitshares was 117,000 BTS, since I was part of AGS.
But as a last resort, and if I don't get it to work before then, once I'm done decrypting one of my hard drives I will do a complete reinstall of Windows too. If it still doesn't work after that than I don't know why.
