UPS Pro test installation problems

When installing ShipRush UPS Pro I never did get the Advanced button in the wizard screen. I have tried scrubbing and reinstalling, but always getting the same result:

AccountNumber can not be found in UPS system [9570102]

When I cancel and then restart ShipRush I got the following error:

Error opening service control manager: 5 (SetConnected)

So (per the forums) I restarted ShipRush as Administrator. But I then got the same Account Registration Failed error.
