SEP 14 preventing clients to open excel macro

Hi,

I have this problem for a while now. I recently configured a SEP server running version 14 and succesfully transfered our clients to this new server.

Everything went smoothly until one of our user tried to open an excel file with macro. The file is open, but displaying nothing.

We are using SEP 12 before migrating to 14 and we have no problem with macros. 

I tried checking and tweaking Policies that may causing the problem but I can't find any option that directly pointing to macros.

Maybe you encounter this too or have any idea where should I start checking?

Thank you in advance.
