Did you receive any other errors before that? There have been a few users that also received an error prior to that about being unable to load TriangulationLib.dll because it was not installed properly on their system. If you were getting that, then the latest build at
http://www.globalmapper.com/global_mapper9.zip should fix this problem for you. Just download that file and extract the contents over your existing v9 installation to fix the issue.
Let me know if I can be of further assistance.
Thanks,
