Can't run astrill again

[ratuljain1991]

Hi I was using the 7 days evaluation version of astrill vpn.So after my trial expired I ran it sandboxed(only the program as I was unable to install it under sandbox) and it worked again.

So now it has expired again but this time when I run it again under sandbox it just says that it has been used on this computer before.So I made another sandbox and tried under it but still it's saying the same thing.

Using the latest version of sandboxie and tis is the program https://www.astrill.com/
