Please take a screen snapshot of the error message. For detailed help you could use File, Archive... in Workbench and attach the resulting .wbpz file to your reply. Please reply with the version of ANSYS you are using (18.2, 19.0).
Here is my pre-stressed, modal superposition, transient analysis. Is this how your are approaching the analysis?
Attached is an ANSYS 19.0 archive if you want to see it in more detail.
I can tell the rotational velocity pre-stress is working since Mode 1 is at 81 Hz and Mode 2 is at 83 Hz. Without the rotor velocity, they would be equal. The transient disturbance is a 100 ms duration, 10 G vertical acceleration.
