I have used Vue for years and Vue 7 infinite since it was released and never ran in to this.

After installing the 7.4 update  I get a couple of issues.
Every time launching it says "Bad activation number". I have entered the given activation number but it continues arguing about it.

Second thing is I get e-on's water marks all over my renders (probably connected with the activation thingy). 

Anyone else had this? Do I have to uninstall and go back to the build before 429999?
Sigh...
