If it is from defender , you can click ‘more details’ —> download anyway. But it never happen to our software anyway. Not sure why. just in case in the future you encounter this and the way to around it.
the new release is fixing a number of bugs. including that sometime you can’t login in.
if you paid with a login, just need to login to use Pro membership. as long as you don’t login on to other netcut, the Pro membership stay with your login. “you can use the login at any netCut , but just one at same time. so if you login multiple place with same login, only the last login one remain active”
