Responding to myself, i tested the Megagames hosted file posted in the wiki (seems the original FilePlanet, IGN? Ad-Supported version) and not only doesn't work with the "No Internet Connection" error (for sure because the Ads Server is gone), in addition it doesn't fully install althought it says it does, because for a weird issue it doesn't extract all the CABs (You have to do it manually).
The mayorgeeks version is the same, but with two different files, what seems a cracked version. And i didn't find an official statement anywhere about this is a official or an allowed version (only a reference in Wikipedia, and that doesn't make anything official at all).
Anyway, the Ad-Supported version has the same problem with the language: It is multilanguage (ENG, FRE, GER, ITA, SPA) but it only plays in ENG because it doesn't add the registry key to change the language above mentioned.
