Why is it every time I upgrade to the new release all my nuts and bolts change and now I have some missing from the library. Is there a fix for this?
I'm not a Toolbox user, but it sounds like you are leaving your Toolbox file in the default location and it is being overwritten by the new version. I suspect that you need to save your Toolbox file into another location, so that it doesn't get overwritten, losing any changes you have made. You may have to got through an update process to bring your Toolbox up to the new standard, but you won't lose the changes you made.
PS. You should probably move this question to the Toolbox forum. The move command should be in the Actions box at the upper right of the page.
The problem with moving the toolbox is that it doesn't get updated with anything new and I always have to move it back to the default to update or to install new version of Solidworks. That gets to be a pain.
