Oh, that exe you found was intended to fix v2010 and/or the 2008 version created for Vista/Windows7. It's only supposed to be used to replace "executedrt.exe" v2010.2.103.1115. Do you still have a copy of the one you replaced? If not let me know and I can send it to you or you can reinstall from www.empirisoft.com/download_old.aspx. The version 2008.1.21 you mention I think is for the file "directrt.exe". The actual release version is defined by the version of "executedrt.exe". The final release of v2008 for XP was 2008.1.13.
Anyways, aside from all that, I ran your input under 2008.1.13 here and it seemed to run fine. But then again, I didn't have the gif files used on the second and third trials. If you remove those two trials (or use some temporary text stimuli in place of the gifs) does everything work ok?
