The tracking server contained in PEEP is old and uses a slightly
different API which is not supported anymore. Right now PEEP only
works with the PEEP tracking server properly, while the Text 2.0
Framework only works with new tracking server properly. The next
release of PEEP will contain the new tracking server as well.
If you want to use your Tobii tracker with the new tracking server,
please have a look at the FAQ:

You have to switch the adapter to "gazeadapter:tobii" and set your
tobii.server to the address or your TET server (either localhost, or
something like TX120-203-83900194.local.).
