It may be due to MediaLab trying to use an earlier version of Internet Explorer than the one that you have currently installed. There may be something else to see if it resolves the issue, but I need to know a few things:
1) What Windows operating system do you have and is it the 32-bit or 64-bit version? You can find out the second piece of information if you click on the Start button, highlight Computer and right-click and then select Properties in the box that shows up.
2) What version of Internet Explorer is installed on your computer?
3) What is the full version number (i.e. ver.20xx.x.xxx) of your copy of MediaLab? You can find this by opening MediaLab and selecting Help>About MediaLab.
