I've been using the HMA VPN client on my new XR500 over the last couple of weeks. It been really useful for fixing latency issues I've been having for online games, on occasion. Today I rebooted my router and, upon going to active the VPN, I discovered that the drop-down menu is now unpopulated, just an empty white box. Same for Country and for City (though I guess that is to be expected, with no service selected). The VPN had been fine before the reboot, as I had switched it on earlier in the day (it was off when I rebooted though).
Interestingly, my username is still active in the username field but my password has also disappeared.
Any ideas what's happened or how I might fix it?
