Video Help?

Does anyone else us ImageMate software with an Elmo TT-02RX Document Camera? I spent my whole prep time this morning trying to create a video demo with that combination, and it would only save the first two minutes of the video! I tried everything I could think of: Googling the answer ("download this software" which is no longer available), changing the settings, talking faster (lol). Nothing worked. I have an email in to our IT department, but they are also new to this technology so I thought I'd ask all of you for your advice. Thanks!
