Getting activation code for Addit Pro for Flight Sim X

Does anyone know how to contact Joseph Stearns, creator of Addit Pro software for Flight Sim X??? I sent a payment to his website, byteforge.com, for an activation code. The payment was processed, but I've never received the code and nobody has responded to any of my inquiries. Would appreciate any help or info. Thanks.

Here is his email.

I ordered AddIt Pro a couple months ago and never got any reply or code. I email him per the website several time and even emailed the webmaster. Still never got any replies. I then contacted him via paypal and they never got a response either. I've had to file a dispute to try and get the money back. It's a shame, I had bought a copy years ago for FSX and decided to get one for P3D but that looks like it's not going to happen. I hope he's ok...

purchased back on the 9th (08092020) I have emailed him three times once through PayPal had no choice but to start the "undelivered item" process. I as well hope everything is okay

Update: PayPal processed my refund today honestly, I would have rather had the full version 😥

azdrac,
Thanks for posting solution to problem.

I also sent a registration fee for Addt pro and have heard nothing but crickets.

I did an internet search and I beleive I found his obituary from March 15th.

The mailing address in the software is only a few miles from the funeral home.

I'll send a request to paypal for a refund, but I tthink I left it too late.
