I only just read it on a.net. None of the news sources have anything, unlike all the press it gives Maxjet when it started operation. Someone on a.net says it has mechanical problem on one or both of the 762.

Also, flightaware.com shows that 200/201 IAD has been running with 752, and even 738, on many days. And Maxjet doesn't have those planes, so they must have been chartering other jets.
