Yeah, this SOUNDS like the reaction I am having!  This IS high contrast film, too.

Well, I hope not.  I paid $350 for the Agfa film over a decade ago, and was worried that a new box would run $1000.  I got this stuff for $9.99 on eBay, but the Ultrafine outfit sells their replacement for $86, which sounds really reasonable.  But, if I can get the right chemistry, I hope I can get this stuff to work.
