HEELP! I have the same problem of markhyboy ( Run-time error ´9´, subscript out of range. Pioneer 105)
prassi primo execution opens fine but 105 are undetectable, then install pxengine 358 and the program runs excellent (now with 105 recognized) several days. The problem begins when Installed a new drive (LG cd writer 48 X). Prassi primo don´t open anymore. I Reinstalled several times and nothing. Then Restore Win XP to one day before the installation of the new drive->results Prassi primo operable again(even with the new LG inside) but 105 unrecognized, if I installed Pxengine 3.58 for recognized drive-> error comes back.
Anyone knows what happend, or maybe is time to say good bye to my new LG drive
