Hi Yolanda,
I’m not aware of anything special about the MRC files from Chimera.  It sounds like you simply don’t have a license to use the part of Amira that reads/handles MRC files, in which case you would need to contact the Amira folks about getting such a license.  Can you open any MRC files in Amira, like from sources other than Chimera?
