Pandora has changed their API, this plugin will not work until the changes are found. Stay tuned.
AH now I understand why it is not working.. Keep me in the loop Sonic please sir.
Ok i've got authentication, station lists, playback, and feedback all working. All that's left really is station creation/deletion. Considering this was a practically a full blown rebuild... not bad. Few more days!
RRPandora 0.7.5 will be released later today. This new build will require .net4.0 be installed on your car PC. Prepare your installation before downloading the new version.
I would also suggest you uninstall any previous version. It's not necessary but its a good idea to get rid of the obsolete libraries.
Everything in 0.7.4 is back and working again. Huge thanks to Mark for showing me back on the right path!
