I really don't see the point in blasting the moderators of this forum. This is Renderosity, not E-On Software. The tools and tutorials they provide as well as help and encourgement do not deserve this type of comment nor the anger taken out on them. I had a problem with reinstalling the 4.12 upgrade also, and went thru the loops trying to communicate with them. Yes the OpenGL sucks and does not work at all under XP, but prehaps the new fix or version will correct this. In any case write or better yet FAX your problem to E-On in France at their address and phone numbers shown in the User manual. If you still don't get an answer, write the Attorney General in Oregon a letter or the newspaper in Beaverton. But lets not involve the nice people here who provide this site. I managed to get by upgrade straight with a few e-mails to E-On Software. I suggest you try again expaining your problems and you have used Vue since ver 2. But I must say.. no answer whatsoever on the OpenGL prob..... but thats a prob for everyone.. not just me and I'm sure E-on will address it in the next release....
