Issue with toolbox hardware after update

Hi,

I updated from SW2016 to SW2017 yesterday, and now I have this issue with my toolbox hardware everytime I save.

When I work on a project that I began in SW2016 that includes hardware from the Toolbox, I get this message everytime I save.

Solidworks wants to convert the old hardware to SW2017 part files - but it can't.

How do I solve this ?
