Error message encountered in truncated DirectRT task (case 27742)

[COLOR=#555753]Hi,[/COLOR]

[COLOR=#555753]I am trying to run a task in DirectRT but after the first instruction page, the task won't continue. After I hit "escape", DirectRT displayed the following error messages in the Performance tracking text.[/COLOR]

[COLOR=#555753]Here are part of the error messages I received in the text file:[/COLOR]

[COLOR=#555753]Would you be able to tell what might be the cause of these messages? When I ran this same task on a different computer, the task was able to run okay without any problems. So I believe the CSV source file was written correctly. [/COLOR]

[COLOR=#555753]Thanks for your help![/COLOR]

Here are a few things that you can try on the computer on which you are having trouble running your files on DirectRT.

1) First, change the screen size setting under the Options button of your styles.drt file to the same screen resolution as you have on the new computer-1024x768. Then try running the DirectRT session.

2) If the problem persists, make sure that all of any names of files in the stim folder are the same as what you use in the .csv input file.

3) If the problem persists, you may try changing all of your .bmp image files to 8 bit color depth. You can do this really easily and in a form that plays nice with DirectRT using a free program called IrfanView. You can download a copy at [url]www.irfanview.com[/url]. Once you download and install Irfanview, simply open your image in the software, select Image > Decrease Color Depth... from the main menu bar, select the button next to 256 Colors (8PP), and finally click OK to finalize the color bit conversion.

I'm also happy to look at your DirectRT files themselves. I would need everything necessary to run it on my copy of DirectRT. Either uplolad them as attachments to this thread or send them to [email]support@empirisoft.com[/email] and reference case 27742.
