Hello, I was having some difficulty with an old program once I updated to the new version of Mathematica. In the program, I'm trying to solve coupled differential equations that involve 3x3 matrices and normal functions.

In the earlier versions this worked but now I'm getting an nlnum error. First, this error is undocumented so it was difficult to figure out what it meant, second the fact that I'm getting the error at all seems strange.

Anyways, I'll attach the piece of code thats giving me the error to this. Its all self contained. Along with the error I'm getting.

Thanks ahead of time.
