thx for help, zoltan
yes, i have a german version.
1: interesting. thx for explanation!
2: i never used that stuff - only cruise control is on, and pandorausername is entered.
3: yes, standard config file. always used that.
4: yep, i tried that and it didnt change anything (officially grabbing but never seen an mp3 in any folder)
what i found out now is, that version 7.4 (the older one, not the "7.9" alias 7.4_4) works again! in october or november it didn't, because pandora seems to have changed anything in their routine (if i remember correctly). but now, after i tried to work with "7.9", i just replaced the jar with the older one - and its working again, although without the new features.
