Hi Guys, hope everyones haveing a wonderful day like me!!

Can anyone point me in the right direction in where im going wrong with this simulation? Iv been using solidworks for about 3-4 months and everything is self taught so far, so i never no if what im doing is quite 100%. We have recently upgraded to premium and im trying to see what happens to this frame with its 1.9t load inside it.  It keeps saying restraints invalid?or somewhere along this line.

Any help would be much appreciated.

Thanks

Robert
