Uncle E at JRRShop is utterly reliable at making good on problems.
However, his site experienced a near-extinction-level event beginning shortly before Black Friday and lasting for about a week. The company that hosted his business crashed and never came back up. He had to scramble to find a new host, get all the bits and pieces re-assembled, deal with more brokenness, and then probably got slammed by the pent-up customers who'd been waiting for him to get back up.
He's a KVR favorite and a regular there, and most of us have done tons of business with him for a long time. I've never, ever caught him in a lie or misrepresentation, and he bends over backwards to take care of you if something goes wrong.
If he says the issue at this juncture is at the Presonus end, you can take it to the bank. I haven't read anything saying that they're hung up, but wouldn't be surprised, considering the software and hardware promos they're currently running.
