Hi Alan,

make sure to first extract the entire RASCAL zip file (including the lib folder) before running the jar file, RASCAL gives this error because it cannot reach the lib, most probably because it has not been extracted from the zip file. Let me know whether that works! For further questions, please also cc rascal@delfic3.nl which is a special e-mail address we have created for Q&A regarding RASCAL, and for obtaining a user account.
