Ok Strange things are hapening.

I upgraded my QNAP 509 Pro to version 3.2.0. Together with this update I got Twonky server 5.1 (embedded in the QNAP version).
Till then Twonky worked fine! Now every time I start Konfig or Kinsky Desktop I have to see if these applications find Twonky.
The strange thing is that on my iPhone Songbook works allways.......
Another strange thing is that I cannot play wav files anymore.... only flac.
Pictures are very curious too. I renamed all pictures folder.jpg and put the conversion toggle for resizing in Twonky on.
I get random pictures. No idear how or why.
HELP HELP HELP. It drives me crazy. Of course I tried everything restart Twonky, my network, reindex, put reindex on a different scheme. ALL in VAIN
