Getting error while importing the solution

Hi,

I am working on MS Dynamics CRM Online. I created a N:N Relationship between custom entity (Project Task) and a system entity (User).

When I export the solution and import the same solution to another CRM Online instance, I am getting an error message called "The content of the import file is not valid. You must select a text file".

If I remove the N:N relationship as mentioned above then I don't face any issue on exporting and importing the solution.

I am also getting another issue related to the N:N relationship when I export the solution from old CRM 2011 Online form to new CRM 2011 Online form (after polaris release).

Kindly let me know how to fix this issues.
