Do you get an error Flamingheart? If not, then just rather A. Re-install FeralHeat, but uninstall FeralHeart before you Re-install it. Backup the certain files you need.
B. If you remember then just put it back how it was before you tried.
DinWolfie, the Gazelle.mesh may not be in there, if you don't really need the gazelle.mesh then just go into the Objects folder, find the group .object file that the gazelle.mesh is in and erase the gazelle.mesh stuff, everything under it until it gets to the next object, which should have the []around the object word.
For example...
[Gazelle]
mesh0=%gazelle.mesh;0 0 0;1 1 1;1 0 0 0;
[Giraffe]
mesh0=%giraffe.mesh;0 0 0;1 1 1;1 0 0 0; Erase the Gazelle, not the [Giraffe] Which is the next object.
Now, if you want, you can give me the file(s) that you downloaded to get the meshes. I can try to see what the problem is and rather tell you what to do to fix it, or upload the fix.
...Sorry if this is confusing.
