Hello Ken Meade,
Can you please provide me with the following:
Computer OS version
Web Browser version
Have you tried logging off, emptying your internet cache, closing the web browser application, before trying once more?
Also, did you know that if you've installed or upgraded to VIRL PE 1.5, then it's not necessary to download those images from the "software.cisco.com" page. The VIRL installation either came bundled with those images, or you can easily have the User Workspace Manager (UWM) download and install them by going to the VIRL Server > VIRL Software page.
Cisco Learning Network
Windows 10 / Edge or Chrome
MAC OSX Mojave / Safari or Chrome
These both come back with forbidden file or application - on both platforms:
IOS XRv 9000 6.2.2
Seems this one have been fixed:
