Has anyone else had this problem?

Every time I try to convert an .mp3 with Swift-MP3 it starts working, gets as far as "track01.mp3 11.025hz 32kbps" and then quits.

Then I get three illegal operation alerts:

"swift-mp3 caused an exception 10H in module swift-mp3.exe at 015f:00402a97."

...twice, and then:

"swift-mp3 caused an exception C0000026H in module kernel32.dll at 015f:bffbfd34."

Is something corrupt? I deleted one version and tried a freshly-downloaded one but the problem persists....

Help!
