Hi Amandeep,
If you read my initial post above you'll see that I'm not having any problems purchasing Premium.
The problem I have is in the way we are being treated. Back when Enpass started, I, and many others, paid extra for what was called "lifetime Pro", which was the highest feature level.
Now, instead of respecting the support we gave, and keeping us on the highest level, Enpass has created new levels (Personal & Family, and Business), and demoted our level (Pro) to BELOW the new ones, (ie we now lack new features), and expects us to pay again to get up to even the LOWEST of the new levels.
Let me know if you don't understand the issue.
