Performance in VR poor; other operation "slow"

I'm logged in here, so posting this, but can no longer log into the site or app.

I've reset my password and can log back in. However, in the software, I get a message that an update is available; but the installer says the GTNXi PC Trainer is "Not Installed" (which it is), and if I try to install, I get the message shown here.
