 Make sure the media engine handle you are passing to the API procedures is valid.
 
 The only other way you might receive errors is because the 30 day trial has expired. Look at the date in the LanScapeVME.C license module you received with the trial. The date in the header shows when the license was issued. If you are 30 days past the specified date, your trial period is over.
 
 If you still cannot figure out the problem, feel free to email us your problem code and we will gladly look at it. If it is a short code fragment you are having problems with, you can also post the code to this forum thread if you want. Also, please tell us the version of the trial media engine you have.
 
 Thanks,
