Run Time Error 13: type mismatch

[jarvis24]

Try this and see if it helps. Make a backup copy of the folder:

C:\Medialab\Experiment Editor

After making a backup copy, delete the folder and unzip the attached replacement folder. The version attached contains the experiment editor files that comes with the v2008 installation package. If one of the files in your installation has gone missing or has become corrupt, using this replacement folder ought to fix it. If the error persists, then I would suggest uninstalling MediaLab and then doing a fresh installation.
