Export Macro Doesn't Work After Windchill Update

Hi everyone. Our IsoDraw 7.3 is still connected to Windchill, but after the 12.1.2.0 upgrade, a lot of macros don't work. Checking in and out works fine. Curious if anyone has ran into this error. I downloaded 7.4, but not sure what the next steps would or if that's even part of the solution.
