Please help me!!! Humidity issues...

I doubt the RI was caused by humidity in the 40% range - I think your vet is dead wrong.

As Alex advised, provide a humid hide. The risks of providing high humidty without adequate ventilation far outweigh any incorrectly perceived risks associated with moderately low humidity.

As I said in my topic, I'll ask him again... However, I had plenty of ventilation(the 1/8 screening was UNCOVERED) at the time, so that was likely not the problem.
