Yees, new objects can be quirky like that.
I've downloaded some of Thierry's stuff before, and she's very good at putting a 'Read me' into her download, along with the actual object files and images.
Reinstalling probably fixed any unseen issues, but next time be sure to follow every instruction in the ReadMe very closely. If it does this crashy thingy like it did to you last time, try retracing your steps. Look for duplicated files, and so on.
It's easy to misplace files sometimes, so be careful, and good luck!
