Former Employer Not Adhering to Their Non-Compete Agreement

I signed a non-compete with my former employer. I am in the 3rd month of a 24 month non-compete. The non-compete stating that I would be paid a specific amount of money for the duration of the non-compete agreement. Last month the check they sent me bounced. They told me that they were in the process of switching banks, which to me means they admitted to sending me a "bad" check. I received a cashiers check to replace that check almost 3 weeks later. However, they did not include the $5 fee my bank charged me for their check bouncing. It is now the 26th of this month and I have not received payment for this month. Legally would this allow me to have the non-compete removed since they are not adhering to their part of the agreement?
