During non-linear analysis on a structure with planar rigid supports with released uplift, I get an error displaying "execution problem no 902". What might cause this?

Please mind the limitations of the modal analysis for non-linear models
See e.g. message 4 from http://forums.autodesk.com/t5/Autodesk-Robot-Structural/Uplift/m-p/3320823/
Thanks! Think I got my answer there. No good idea to combine non linear supports and seismic modal analysis. And since I'm not about to do a time history analysis, I guess that leaves me with the mentioned method of transferring results from the seismic analysis to a separate model with non linear supports.
Thanks a lot!
