[DMDX]  I am having problems running an experiment on lexical priming in LSM. I do all the tasks in TimeDX and when I try to check the syntax it says:   Couldn't not Creat/OpenRegistryKey/DMDX/3/LastUsedItemFile>ErrorCode5   Once I close that window  appears another once that says the same but now on top iof that it says:   TUne some values for anticipating the vertical retrace.   I believe that I have already tuned all the paramters up. My video clips are 640x480 32bits, the programme says that, my tuning parameters have been set that way, but all the same the window says that i have to tune it up.   I had a similar problem and Deb showed me how to fix the problem in my lap top. But now that I need to set the programme in the lab's computers (Dell) I am getting this messages. Does it have anything to do with any kind of restrictions that this computers might have for being part of the university's network?   Thanks for the help, -gerardo
