Cannot make downloads with Download Manager

I have problem while I was downloading a file. I was using the Internet Download Manager and upon downloading a trouble interrupted. A box of message occurred stating that; ''the Internet Download Manager detected that its registry keys have been damaged since the last run. It's possible that you run a flaky spyware remover program with corrupted program registry. Internet Download Manager will try to restore all damaged data, but some data may remain corrupted.'' Upon reading it, I'm thinking that the IDM is damaged. Can someone help me with this?
