Urgent, error on simulation

hi,

Im doing a project for university and im having serious problems running the motion simulation. After i mesh all parts, select the material, select support and load conditions, i start the running process and when the bar reaches the 32 % it appears "model geometry might be changed" and something about not having restraints. Im working on this project for about 3 months and im not a pro on solidworks so im asking anyone who can help me solving this problem.I have till 17 january to present the project so if someone can help me i

thank.

I will attach all the parts and the assemblies if someone needs it. The final assembly you need to open is ASSEMBTOTAL3, its the final assembly.

Te error that appears is " model is unstainable.Restraints may not be adequate"
