Abnormal Termination: mdrv process termination LR 12.02

I am receiving 2 types of errors. The first being that Loadrunner is having problems pressing buttons. It seems that 90% of the vusers I run fail at a step where they have to press a button. I have tried a fresh install of Loadrunner and re-recording the script, but neither of those work.

 

My second error is probably caused from the first error. I am seeing users being dropped off of a load generator with an error of mdrv process termination. I have run out of ideas to troubleshoot this, and any help would be appreciated.
