Run time error '9': Subscript out of range (case 495)

[Dan123]

Hello,

I'm running MediaLab 2008. I've recently placed a pair of .AVI videos into a study by linking to them directly in experiment editor (No embeds, no URL links). They play fine, but if any button is pressed on the keyboard during playback it causes a runtime error (error '9': subscript out of range) to pop up, followed by a complete crash of Media Lab. This only occurs during playback of the videos, before and after in the questionnaires I have had no problems. I've duplicated this problem using a .MPG file type as well. If left alone, the whole video will play and everything will progress normally. However, if the participants press anything it will crash instantly and we will have to restart.

Any ideas about what is going on?
