Adding MIB's

Adding MIB's

Hello, I have downloaded some MIB's for Imail and Sony and want to add them to opmanager. I have putted the files in the mibs folder and when i click on load MIB, they are visible in the list, but when I select them and click here on load (see printscreen) , the file isn't loaded.
Does it maybe have to do with the evaluation edition or something else maybe?
Thanx in advance
