I'm new to ETH. Just downloaded Mist 0.8.6 + Geth 1.4.18 and started geth.exe with these parameters:
geth --datadir C:\TMP\data --fast --cache=1024 --jitvm --jitcache 128
In Mist I saw a sync to 100%, but then it went back to 0% (and 1142 blocks remaining) and geth started to download some states.
But now it seems to be stuck in a loop:

Restarting doesn't help. The data dir has a size of 11.1GB.
What can I do now? Thank you!
