MediaPortal Plugin Compatibility Check don t work - Rockstar Plugin (2 Viewers)

[Entdecker]

Dear Developers,
I try to use "Rockstar" Plugin whis MediaPortal 1.18 pre (and 1.17) unfortunaly the Plugin does not work.
Ministerk told me it is a MediaPortal 1.18 and 1.17 problem because they not detect this incompatibility.

Logs for this problem you find here:

Rockstar - the ultimate online music plugin (Spotify&Grooveshark&Rdio)

Thank you Ministerk to help me to find the problem.
