Help with a Vpn (Vpn related but more relevant here)

Hi,

this is a vpn related post but I couldn't find answers there so I am posting this here. I am using windscribe but I sometimes change accounts. Windscribe has introduced a security system which gives an error when you change your account. It says you had signed up with your original (previous) account and your original account has expired and we will not let you sign up with another account to bypass the free 10gb limitation, either log off from the previous account or upgrade it to Pro.

I contacted Windscribe support but they couldn't help. I tried removing and re-installing windscribe several times and even deleted my browser's cookie history (if it store the data that I logged into windscribe with the previous account) with bleachbit but to no vain. Windscribe somehow stores the data of your previous account and I can't log off from it. Windscribe support told me to format the device but that sounds too much of a hassle just to log off from that previous account.

Would you have any suggestions on how to bypass this? So that the new Windscribe app I install does not know the previous account login.
