Maybe I clicked Mac version or something...guess has to be a simple explanation. (yes they had billboards folder and a perspectives folder  in the zip)(I dont know what they are)

(all the other plants I have bough had a nice neat VOB file..just drop it in it and go)

these were the offending files:

Item: Senegal Date Palm (by Xfrog Inc) Cost: $14.95
Item: Coconut Palm (by Xfrog Inc) Cost: $14.95

(and yes Im a lazy person...basically Im finding out you only need 2-3 really good trees to make a killer wide shot).......So I figure Im gonna buy them (a set for jungle, a set for regular forest etc...)LOL
