Uninterpretable Error Message

[Lang_Lab]

Hi there,

I've just created a .csv file that displays .bmp images and requires voice responses. It works fine on our older laptops (Windows XP, DirectRTV2008) but when I transferred it to our newer laptops (which have Windows 7 and the DirectRTV2008 that is compatible with 7) I get a strange error message talking about conversion of strings to Uintegers. I have no idea what this means.

When I open the input file, I get that error message and once I hit OK, it does take me to the first screen of the experiment. Once there however you have to close the program as it won't let you go any further.

I've attached a screen shot of the error, the .csv file and the style file. I've tried changing the screen resolution (as of now it's set to the size of our monitor) but it hasn't changed anything. I'm also running another input file with many of the same .bmp images and it works fine, so I know it's not the images.

I would appreciate any advice!

Thanks,
Erin
