Thank you Luc. These resources helped me get past the first problem.
I am still not able to run any of the tutorials. In each case, I get an error indicating a missing file.
For example, when I try to run VisibilityCheck.java, I get: "unable to find file /assets/org/orekit/IERS-conventions/2010/nutation-arguments.txt". I even tried copying the assets directory to "C:/", but still no luck.
How can I get Orekit to look elsewhere for this and other files? I've followed the advice in the Configuration help page, but can't seem to make it work.
Thanks for your time.
