Tried posting the log files, and it says it is to long.
You'd post them in pastebin usually and link it here.
I did notice this in the log
2016-08-25 11:17 (ERROR) -- ArmoryQt.py:2817 - ***WARNING: Wallet could not be loaded: C:\Users\hien hoang\AppData\Roaming\Armory\armory_Y6F3gLf_.wallet (skipping)
So it failed to read your second wallet. Feed this wallet to the recovery tool, it should fix it. Post the recovery log as well.
Also, did you by any chance saved a comment or user defined string input with non ascii characters? That would break the deser method.
