Hello David,
Thanks again for replying 
.
I checked your suggestion. It appears that there is indeed a problem with the animation file because the animation does not play in the pview even though the model is displayed . However if I export both: the model and the animation together in one egg file then it plays the animation properly. I guess this will be a bit heavy but I think it should be workable.
Thank u once again.
Regards,
Dev.
