win or linux?
I'm connected to the network but not downloading any blocks?
Windows 7. I tried deleting everything in appdata/roaming aside from my conf and wallet. I left it over night with 10 connections and it's still 42 weeks behind just like it was when I started it
I had that issue on one of my Win7 machines a couple of weeks ago. I solved it with brute force, rather than finesse. Unless/until you get better advice, consider (in no particular order), after making suitable backups:
Let it build from scratch, including a brand new wallet, then overwrite the new wallet with your existing (backed up) wallet copy, if appropriate. (Is the wallet empty anyway?) I found that some of my old wallet backups were not reliable, for no obvious reason, while others were. I think with hindsight that some were made during a long-ago dead-end fork.
Try the Upgrade QT Client tab in the Wallet window.
Try the Rebuild Blockchain tab in the Wallet window.
Try any of the rebuild tricks you might do with your other coins. GRC is similar yet different - there is an MSI file to try, for example.
Try one or more of these a second time. I know it sounds like superstition, but sometimes it seems one attempt will fix something and the next will do the actual rebuild, sort of like "when in doubt, reboot Win7".
Oh - Are you seeing the Mining Module window? If so, what version number shows (near the lower pie chart)? Mine shows version 168 at the moment.
Edit: afterthought - is there anything interesting in your log file? Any clues there?
