Hi Rinu,
You had a couple extra columns in your input file that were unexpected and a couple an unusual order. Take a look at the attached revision and see if it improves the situation for you. You might look at the samples in "C:\DirectRT\Samples\4 applications\standard priming" for samples similar to your own. Also, I noticed you were trying to get a 2000ms delay after each trial--you can set that in the style (.drt) file located within your experiment folder. If you don't have a style file, you can copy one from one of the sample folders and modify it as you like.
