[solved] "unusual" runtime error
My name is Kevin and I am trying to run an experiment in which every trial presents a sequence of videos to the screen. Trials are organized into blocks, which are organized into phases. There are 3 phases, each with 4 blocks, each with 8 trials for a total of 96 trials. I am looping through each phase, each phase, and each trial.
The experiment runs great for a while, but every time I run into one of two runtime errors: either an error that says it cannot load a video file and that I should make sure the file type is supported and that it's in the file pool, or the following:
Program: C:\Program Files\OpenSesame\opensesame.exe
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application’s support team for more information."
Every time I run the experiment the error (one of the two) comes up at the same trial. (I tried running it on a different machine, and I still got an error but two trials earlier than I usually do, whatever that means.)
Here is what makes it really weird: every time I receive this error, all of the videos in that error-producing trial have been presented with no problems before the error appeared (in fact, it's really just a few videos that repeat in different combinations over and over). In addition, the error comes up in the middle of a block in the middle of a phase, so it's not an issue of changing loops. In fact, there is nothing different between the trials that come before that particular trial, and the ones that come after. I have the dictionary for each trial printed out as the experiment progresses, so I can see exactly what OpenSesame is trying to present for each trial, and there is nothing wrong or different from all the other trials in the trial where I get the error.
I should also point out that every time I get an error message like that, OpenSesame crashes.
I have no idea what the problem could be, or how to troubleshoot (other than print out exactly what videos it's trying to present for each trial, which I'm already doing).
I would greatly appreciate any insight or suggestions as to how to figure out what's going on and fix the problem.
Thanks so much!
