... When I run it, I get the message to the effect that the row 3 has an error in LOC (location) column. But when I review the file, I don't see anything that is extraordinary in the row 3.
In row 2, you've got double quotes around your text stimulus. Try removing the double quotes and replacing them with a single ~ characater at the start of the string, i.e., instead of

"We're interested..."

try

~We're interested...

Double quotes, commas, and to a lesser extent, single quotes can sometime interact with other input file attributes to cause a problem when DirectRT tries to read the file. Additionally, the lack of a ~ in this case would have DirectRT looking for an image file called "We're interested in how well you can learn these pictures..."!
