No I didn't send my PRS500 to Sony since I'm not form US and I tried with Calibre 0.6.29 bit I have
this problem.
Software from the CD that came with the PRS-500 (v1.1) won't install. Maybe I'll buy that Sony's own memory card system but for now I'll use another older computer that still has XP on it and I'll try with Calibre 0.6.55.
EDIT: OK I installed Calibre 0.6.55 but how do I get to PRS500? You said I can find the needed drivers in the 'driver' folder inside the folder where you installed Calibre (most likely c:\Program Files\calibre) and I found them but what now?
