PRO = the old version of the paid version, unfortunately, for today it is updated much less often than the usual version.
VIP = this is the status of the user in the regular version, a new version of the "paid version". Authors of the program from the sale of the paid version of the program (Pro) have moved to the direction of paying a subscription for a particular user for a certain period.
Both Pro and VIP options are spared from advertising and advice, what other forums you might be interested in. But in one case, the "pay" link goes to the program (Pro), and in the other to the user name (VIP).
In the apk-file of the VIP version posted in the forum, it is possible that the user's VIP status has been disabled / hacked. But it may not work. This is necessary for the authors of what they spread to clarify.
If you previously purchased any paid version of the program before the introduction of the VIP subscription (in fact, there were several of them historically, such versions), you can apply electronically to the authors and they will assign you a VIP status, you will have to send screenshots confirming the payment (in Market history is preserved).
