Replayer not displaying data

Hi,
I am not able see the display of data while replaying data files in MC_Rack.
I set up my Rack as: Recorder > Replayer > Display.
The replayer shows the correct no. of streams being played, but the all windows in the display remain blank.
Please help.
Vini.

P.S. I am using MC_Rack 4.0.0. The files have ~ 25 sweeps, recorded with trigger, each sweep is of 500 ms duration. The trigger is also saved in the .mcd file and the display window setting is 'start on trigger'.

Dear Vini,
could you send me a mail and I'll tell you where you can upload the file and the rack so we can have a look at it (hofmann@multichannelsystems.com).

Best regards Frank MCS
