DirectRT quits during RWG

[polysemyboy]

DirectRT is quiting at random spots within a RWG block I have created. I do not think DirectRT is crashing because the experiment exits on its own without creating any trouble and records a data file. The resulting datafiles let me know that DirectRT is quitting at random places in this block: it doesn't quit continually on the same trial and it doesn't quit after the same number of trials each time.

I am running DirectRT2010 on windows 7 with an Intel i5 core processor. I am attaching the input file, the style.dat and a few data outputs to show that directRT is quitting randomly within this block.

If anyone could help, I would be very appreciative.

Thanks in advance.
