Unannounced Departure of Xselerator?

Does anyone here know where this very good tool called xselerator
dissappeared? I had advocated for this product to many companies i had
worked for before and I myself have been using this for like 8 years
now. Looks like it no longer exists.
I had a licence which was called "temporary full licence for 40 day
grace period" Which expired, and there is no support for this anymore.
Bit of a downer. All the money I put on it has gone into the bin.
