I've been using the dbpwerAMP player, Converter, PowerPack, File Selecter, and Aux Input since May of 2001 with virtually no problems. My computer - OS Win98SE - Processor PIII 800mhz - 640 MB RAM.

I wanted to update the player from v1 to v2.1 and the converter from 10 to 11, keeping registered PowerPack 3, File Selecter, and Aux Input so that I could then download/install Sveta Portable Audio.

I uninstalled all dbpowerAMP apps, defragged, downloaded v2.1 player and v11 converter, but idid not install because I saw the 50ComIUpd and DCOM98 links and thought I needed both of them. I tried installing 50ComUpd but got a popup box from Windows saying it was already updated. Then I installed DCOM98. Then v2.1 player, v11 Converter and all the rest mentioned above. I rebooted, then tried to play a .mp3 file. I get an 'illegal operation' every time I try, but if I don't close the warning box, I can hear the music play through with no problem in audio quality. I never see the player. This current install of Win98SE has been running (as hard as it is to believe) for almost 3 years and I can't even remember the last time I saw 'illegal operation', much less the 'blue screen of death'. Below is what the illegal op says.

AMP caused an invalid page fault in

The Converter 11 works fine. I need to get this resolved so that I can install Sveta Portable Audio. dbpowerAMP has always worked extremely well for me, untill now.

I know very little about software but can/will follow instructions or suggestions.

Please help.

Problem solved.

I uninstalled all dBpowerAMP apps, rebooted, defragged HD.
Since Windows was having buffer overflows every time that I started the dBpowerAMP r2-1 player, I thought it was most likely a Windows problem. I recalled reading a few months ago about malware that caused buffer overflows in Windows when various media players/jukeboxes were opened. SANS Institute had issued an alert. I looked it up on their website. My WinAmp, which I use very rarely, was an old verrsion and vulnerable. I uninstalled it. Then installed the dBpowerAMP r2-1 player, rebooted, and played a .mp3 file. No 'illegal operation' from Windows popped up with the buffer overflow info that I listed in my original above post. Problem solved, installed r-11 Converter, purchased the SPA Release 4 with Power Pack, installed it. All dBpowerAMP apps running smooth and trouble free. The best player/converter package is dBpowerAMP.
