I did my install before the patch came. Guess it could be that aswell, but it wasn't the problem yesterday atleast.
I've already tried several fresh installs as stated, but I'll go ahead and try both.
Update:
I used the "Scan and repair" option in blizzard launcher, it scanned my files and said no repair was needed. Installed hearthbuddy and same problem. Tried to uninstall both again and installed Hearthstone and then Hearthbuddy. Same problem.
Update 2:
Added a new logfile.
Update 3:
Logifle didnt seem to stick on a reply. So I'll post it here.
