I had 4 email accounts before upgrading to em version7.
Now i can only have 2 email.
but em disabled one of the account that i need to be activate.
how do i do that.

Hi VirtualN,

If you do not have a lifetime license for eM Client, you might have to buy a new license for version 7.

The free version of eM Client supports only 2 e-mail accounts.

As stated above Ver 7 Needs a new license (Ver 6 Professional  cannot be used for ver 7) 
Assuming you wiill not upgrade the license
To activate the most important email account  go to
Menu-tools-accounts
   and delete one that you do not really need. (On right look for garbage can)
   Then add a new email account that you really need for the 2 account limit.

How many email account does the lifetime license for em client has??

A lifetime license (paid) is a pro license for aurrent and all future versions.  Number of accounts is unlimited.
