I have just re-installed the final version of inscape but I am having trouble with the environment builder.  Everytime I try to open the program, I get an error message telling me that it can't find a valid license. A dialogue box request me to send information to inscape-license@inscape.com which doesn't seem to exist.  What am I doing wrong?

Also the panorama and animation builder do not work.  They fail to open.  Everything else works fine.
