I am having windows 7 issues too, but more with the browser. If I select the hi tom pad an d try to insert a sound from the disk submenu it will not load. Instead it keeps loading Aicd SD1. The funny thing is once the program bombs every other pad I select to drop samples on will also get acid SD1. I'm working on a test case to send support for this.
I have sent a report...
Everytime I load a sample on the pad 2 and select my sample on the disc, it loads Alien Sircuit SD1, but the sample name is shown correct in the Studio page...it only appears on the second pad.
