Indesign Application Issue

Im not sure why, but for some reason, Indesign functions are not working properly. Nearly all functions will not work at all; I can't create new documents, save old ones, I can't use any of the tools provided. likewise, I can't download Indesign files because of an active "Modal dialog" that I can't locate. Is there something I'm doing wrong? Is there some kind of virus or something in the app that is causing problems? I should also point out that I can't quit the app either becuase of the same active modal dialog. This is especially frustrating, given that any google search related to gettin rid of modal dialogs only results in tutorials on how to build modal dialogs, and shows nothing about this sort of problem. 

Any help that can be provided is appreciated.
