Nitro Pro keeps crashing

When I try to edit a page it causes Nitro Pro to freeze, then crash.  I've had this with large files before but now it does in even on small files.

Hello @CWH Designs LLC,

Thank you for reaching out to us through our Community Forums!

I recommend that you repair your Nitro Pro via the Control Panel > Programs and Features. Please reboot your computer before and after running this repair to ensure that there are no ties to Nitro still active in the background. You may refer to this article: http://kb.gonitro.com/knowledgebase#/search/repair/000001641 

If that did not help, please provide the Nitro Pro build (format is 12.X.X.X, e.g. 12.0.0.112) you are working with. You can find this out by clicking on 'About Nitro Pro' under the Help tab or you can go to Control Panel > Programs and Features.

Thank you very much in advance and I am looking forward to hearing back from you.
