One works, the other doesn't
 

Hello!

Running Win 7 Home premium 64 bit on a Sony Vaio E Series.

Have 2 HP W2071D monitors connected using 2 Sewell USB Display adapters (Minideck) [USB to DVI Adapters].

They are plugged into a Sabrent USB 3.0 10 port hub model HB-RUS1.

Have updated to Display Link Mgr. v 8.2.2152.0.

Up until yesterday, both monitors worked fine. Now, one works, the other doesn't.

Tried changing the USB ports. Still, one works, while the other doesn't.

Any suggestions? What is the correct way to try handling the install from scratch to perhaps get it to work better?

Thanks!!
