I purchased two upgrades on 7/22/24. One upgrade for me, and one upgrade for a friend. Both were paid for via my Paypal account. Paypal shows the two transactions. I received about 4 emails from JRiver with MJR files attached. While applying the upgrade to my machines I noticed that they were registered to my friend's account. I was able to correct the license on my machines, so there is no problem. I will use the MJR file which should have been sent to my friend's email address to upgrade their machines.
It would appear that JRiver is sending all purchases paid via Paypal to the Paypal email address, even when the order was done with another user's JRiver account information.
