Maniaplanet Installation on Uplay (for Lagoon Beta) FAILED; Uplay-Maniaplanet and old-one crash after clicking "start"

[Frankthetankmp]

To register for the Trackmania Lagoon Beta you need TMTurbo...
Well I have got it. But the registrationpage does not found it because I have not installed maniaplanet on steam or uplay.

How can I register?
-I have TMTurbo
-I haven´t Maniaplanet installed on steam or uplay
