I did update to 1.1.3.8c but the wallet never starts. It's been sitting for more than two and a half hours at "Loading block index".
Id did the wallet cleanup process after I installed the latest.

Should I just revert to 1.1.3.7 for now?
The wallet seems to consume up to about 1,7GB of memory before going back down to about 1GB, and just going in circles with that.
