Sorry I'll blame my head cold for missed reading your post.
Still I would reflash the pic and start with the second method to set the start address in the wiki.
If your dongle is setup with Pixelnet you can't use DMX software to program it. It has to be software setup to use Pixelnet.
The Lynx Address Utility, StartPattern, DMX Deck won't work since they are all DMX programs.
Which Dongle are you using? USB Lynx Dongle or EtherDongle
If you are using USB I could mod StartPattern to use DMX or Pixelnet (Lynx USB dongle Only)
If EtherDongle than use your Sequence software and set Channel one to 193
