Environments Problem

I have been downloading skyboxes and environments from coastergames.net.....i copy all the items in the winzip into the environments folder but all the skys are coming out orange...does anybody knnow why this is happening? someone please help me...this is annoying me very much! thanks

according to posts at Coastersims.com. (still down as far as I can tell) that was a bug in version 1.2b...there is now a new beta v 1.2b-2..which fixes this problem and others. available at http://www.nolimitscoaster.de/ under the Progress button.
