Hello sketchucation

i have a serious issue with layout.

After I transfer a 2D Drawing into layout and make a change to it like adding a text box, or updating an existing text box, layout crashes, every-time. In order to to get the drawing completed i need to re-open the file and make a change, save it and then try make another change which causes layout to crash and then reopen it and make another change and save it etc. which as you can imagine is really time consuming.

i am running a on a MAC. using skethchup pro 2015 and layout version is 15.3.329

please help

thank you
