HI Gang,

Can anyone offer a little advice?  

I was using an older pc to run aruggeri's MIDI program but the pc 
started to crap out on me so I sprung for a newer model. I'm using 
the same Win98SE software but this sucker just won't load the MIDI 
software.  I keep getting a message that the program destination is 
locked. I swear I've looked in the bios a dozen times to see if 
anything wasn't turned on but it looks ok. Only difference between 
the 2 pc's is I used a sound blaster card for the older pc but opted 
to use the 'on-board' sound board and port of the new pc. Outside of 
this, I'm begining to think the AMD processor of the older pc might 
be a little more software friendly than the new Intel. 

Any thoughts on this? Anyone ever have this problem?  ....or a fix? 

This is a stand alone pc. No internet, just me & my music, some mp3's 
and recording software.

Thanks.
