Ricarda,
This is Jason Reed, the Customer Support Manager at Empirisoft. I will be happy to help you out. It would be great if you could elaborate on a few things for me to help get a sense of where the issue with this blank screen may be:
1) Exactly how and in what order are you running the attached .csv files? Are you opening them one at a time using only DirectRT? Are you running them as part of a MediaLab .exp or .que file?
2) Exactly which of the attached .csv files is showing a problem with the black screen appearing when you first open it or them?
3) Do you have all of your image, text, and stimfiles in a folder named stim? If so, is that stim folder in the same file folder as your other DirectRT input and styles.drt files?
