mmie object not found

Hello all,

I have created one Zen design studio. And in that I have use custom css file for cross tab formatting. Now I have published the same to portal.

When i run the dashboard, it gives me below error. 

"mmie boject: crosstab2.css not found"

I have put my css file and zen file on cmc is same folder and have assigned category as mobile to both.

Also i have put my css file in repository folder.

Is there any other place where I suppose to put my css file?

Thanks & Regards,
