I am trying to synchronize the scanner and presentation but i am having problem doing so. When I try to re-enumerate the inputs in presentation Cedrus Lumina vanishes from the list… and if i insead go to the setting under fMRI mode triggers and try to test the trigger… I get this error message:
Error creating port input channel: “Trigger channel”
Unable to open port COM1.
Windows returned the following error:
Access is denied
I have the XID from 2011-12-07 installed.
Do anyone have any idea of what might be wrong?
