r/BlueIris

So I've been using an old version of Blue Iris for years. I recently went to upgrade to the newest version. Went to their website blueirissoftware.com. Went through with the purchase, and then received an email that just says "Contact Merchant for License". I've emailed both emails listed on their website under contact. I get no replies whatsoever. SO I paid 100$ and got no key, and there is no way to contact them???? How is this software so highly regarded by people???

Has this happened to anyone else? I'm about to just stop payment and find some different software.
