How about changing ContourStyle -> {Opacity[0.3]} to ContourStyle -> {Opacity[0.0], Opacity[0.3], Opacity[0.3], Opacity[0.3], Opacity[0.3]} ?

comment Plotting points given by user in a CDF Player Manipulate
Which version are you using? On V10.0.1 .cdf works without a problem. Have you tried quitting the kernel first? It might help.

comment Solve wave equation using DSolve?
Here's an awkward question: shouldn't the wave equation have a second order derivative of x insted of the fourth? Have you seen this one mathworld.wolfram.com/WaveEquation1-Dimensional.html

This would require adding addition variables con1, con2,... in the revised1 function just as I've defined the dependence on k1 and others.

I've seen the changes of the plot and they are very small. Perhaps one could change the initial conditions for a "better" result (less static one).
