Thanks for the update Sean, much appreciated and good luck with your study. Please keep us updated in case you do come across the same issue again or any other issues.
Note the version history for MediaLab v2010.2. Even after the fix above, there was an outstanding issue regarding passwords (parameter x on Instruction screens). These screen would appear blank but this issue is now fixed as of 2010.2.19 posted Feb 17, 2011.
