CFR and CTR's crash RCT3

Hey guys, I've been trying to install multiple CFR's and CTR's into RCT3 and everytime I go to open them, the game crashes claiming it's missing files 300 - 309. Any ideas as to why it won't work?

The ones that crash are the B&M extended (both normal and inverted) as well as the Nightflight Wing train, RR's Drop Tower, and various Net2Go CTR's.

You probably have accidentally installed the files into the wrong file locations. Try reinstalling RCT3 (to remove all CTR/CFR). Also, when you redownload custom stuff, don't save it right away. Put in on your desktop and manually move the files to the correct location.
