istraxx_ups configuration page blank in VM3

[leonardimfg]

 I inherited an old Joomla 2.5/VM2.5 shop that hasn't been updated since it was created in 2012-13.  Created a test site and proceeded to apply updates.  Hit a few snags (site was originally in en-GB, changed it to en-US).  Doing a test transaction, and failing to get a shipping method , get

Code Select Expand

We are sorry, no shipment method matches the characteristics of your order.

Turn on debugging and get this message:

Code Select Expand

vmdebug UPS _handleResponse XML ERROR: Var1:
Cannot select UPS shipment
Info : Invalid Access License number

Go into shipping method configuration to see whats listed, but the page is completely blank except for

Code Select Expand

Shipping By
Shipment Method: istraxx_ups

Is this just caused by the plugin being out of date?  Plugin is ~2.0.2 I think, while site was updated to J3.6VM3.0.16

You probably need an update for the UPS plugin.
