I recently had to wipe the hard drive clean on one of our laptops. MediaLab had previously work fine. I had to reinstall DirectRT and Medialab. DirectRT works great, but I'm having trouble with Medialab. I reinstalled Medialab. I can open it, but when I try to run an experiment/questionnaire all I get is a blank white screen. I have tried running different experiments, but the same thing happens. I tried to create a new experiment. Experiment editor will open, but will not start a new experiment or edit an old one. Please help! Thank you.
