I"ve set the new one up to TAKE the .lwa file as a parameter... so the new one should work for you either way.
And yes, swiftled is the newer version of bloodywiz... (not that you asked, but..) when I originally named it, it was named bLedWiz... I was lazy and just added a b to the ledwiz name for testing purposes, then as a joke I started calling it bloodywiz... since I've continued developing it, I figure I should get away from using a name that's evocative of cancer symptoms. The new name is mostly based on the fact that my development environment for the app is Flash, so the resulting flash files are .swf. I don't know how swift it really is, but since it's flash based the name's fitting enough.
