Firstly, Do a modal analysis on this model with all supports that you are using in static analysis. This will show you the sufficiency of supports (or lack of) in the model.
Next, once there are no zero-frequency modes in your model, run the static again and see if it runs. If it doesn't check the solve.out file and search for errors in that file, then check for those errors on the forum, if you do not find any answers, please post just the errors in the solve.out file here.
