Before buying question

I have over 11k articles that i want to migrate, i am using pro version but on all the tests i made the component does not migrate all articles at once (probably cause a server time out) and the problem is that if you try to migrate again then the k2 items and categories that has already migrate it remigrates again with another alias. That is a problem cause now lets say for k2 category "announcement" have multiple Joomla categories (announcements, announcements-176552940 etc) with different aliases and with each one portion of the items included in the k2 category. I even changed the limit in the controller from 60 to 5 or eve 1 but again the same happened. Is there a way you make the component continue from where it stopped?

What is displayed in this module? Are these users who are currently logged in, or is this a list of all users from which we can choose which user to log in as?

Is there any way to modify the language on the page? The text is "Press correct password to read post". This is confusing as there is nothing to press. It should read type or enter and there should be a clear box to fill in the password, which is not easily viewable or eminently clear at a glance. And unlock should say something like submit or click here. I'm guessing this is in the code, and not editable, but just checking, thank you!
