Keyboard not registrating on Mac

I have a MacBook Pro, mid 2012, which I recently updated to OSX v10.9 (Mavericks). Ever since the update, Whatpulse is not registrating all keys from the keyboard; it’s only registrating the shift key. I added the Whatpulse in the Accessibility section. The mouse and trackpad are working fine… What can I do to fix this problem?

Mavericks is not supported yet, please wait for 2.2.2. Also please use the search function before posting a new thread, there are several threads where Mavericks is mentioned.

Ok, great! Thank you for your reply!
