Hey Mike,
If you're investigating a bug related to TurboActivate, then your best bet is to use TurboActivate 4.0.2 -- it has a ton of bug fixes and improvements. And it also has a ton of new features.
If you just lost an old copy of 3.4.6 and you're not ready to move to 4.0.2, then you can just shoot me an email at wyatt@wyday.com and I'll send you the old class.
