I'm trying to use ODE45 to solve the vibration equation of motion Mx''+Cx' + Kx = Fsin(w*t)?
If there is an alternative way of doing it then that would be more than appreciated also

If you want to give it to ODE45 you need to write your equation as a first order system. Assuming M to be an invertible you can easily solve the problem.

Ordinary differential equations can be solved in following ways:
As addressed by you, using ODE45
Using Simulink
I would suggest you making use of Simulink for easy and hustle free results.
