I recently upgraded from SW 2014 to SW 2015. and it was working fine until recently i opened some assembly's and SW told the files where missing and i had to relocate them. Thats fine if it happens ones but i haven't moved any parts so why can't SW find the files? It also happens to assembly's i just made 10 seconds ago. I close it and open it again and SW tels me the parts are missing.
Could somebody help me with this problem?
