Same problem as Ethron. I had nero 5.5.5.4 running fine with XP, then upped to 5.5.5.6 and lost my DVD & CD-R. Manually removed all Nero traces, yet still can't recover D or E drives. Get error code 19 in hardware mgr, corrupted registry. NEC DVD and Sony CRX 140E are recognized, but won't allow a driver up or reinstall. Have tried everything. No Win burn update installed, ASPI(4.60(1021)) is fine, I also ran Clone, Padus DJ, BR/BW, CDRWin, & NTI with no probs until now. Any manual reg entries to fix this would be appreciated!!
