The "License Acquisition" is different from the "FrostWire License Popup" message box. The License Acquisition is a WMA/WMV DRM License check.

A little advice, DO NOT download these types of audio/video content. (WMA/WMV Files are dangerous to download if you do not understand how to protect yourself against them.)

And also, the License acquisition popup that you have described (using activeX and also coming from p2ptips.com) is well known to contain spyware, adware, malware, trojans and/or viruses.

DO NOT install the activeX component that you are asked to install.
