I do have some information for you about why the HMA VPN is no longer working correctly. I will paste it below for you.
If you have upgraded from previous Windows versions to Windows 10 and experienced unusual connectivity issues with HMA VPN, you will find this information helpful.
Things to try first
1. Uninstall HMA! Pro VPN, then reboot your system. Install HMA! Pro VPN again and check your connectivity with various apps, while disconnected from VPN as well as while connected.
2. If the problem remains, try the following:
Run cmd.exe as an administrator and run
netsh winsock reset
Then restart your PC.
Still not working? Run this commands:
ipconfig /release ipconfig /renew netsh winsock reset catalog netsh int ip reset reset.log hit
Why is this happening?
This is due to Windows 10 being unable to properly apply the network configuration of a previous Windows version to Windows 10. You might also have experienced other problems with Windows 10 that don't relate to connectivity issues (i.e. search in taskbar not working, Cortana not working, cryptic error messages) - updating one Windows version to another rarely results in a stable and unproblematic system.
The cleanest method to resolve Windows 10 issues after updating from a previous version is to do either a new "clean install" or a reset of Windows, however this would result in losing all data on your system drive.
