OT: Phatmatik Pro?

...wicked
Sorry for the OT post, but I have an way old version of Phatmatik Pro on some ancient projects that is glitching out terribly. I wonder if upgrading to the last good version (1.5.2 IIRC) would resurrect it, but since it's discontinued I don't know where to find an old used copy. Where might someone find a legit version of that to buy now that's off-market? I tried amazon and ebay to no avail.
 

Izotope support still has an option for phatpro - even though it is no longer supported. Might be woRth contacting them to see if you can work out a download link for their latest version. I am guessing you purchased from Bitshift - izotope bought the product, released an upgrade or two, then abandoned it. I still use it and love it but it is long in the tooth and can blow up a project if not treated with care.
Best of luck
