Hey Guys,
I know i'm far behind but I just updated from solidworks 2017 to 18 SP3.0.  All seems to have gone perfectly except for my Feature works.  It just doesnt work at all.  It worked perfect before the upgrade and now nothing.  Not sure what went wrong (I'm sure its something I did).  I'm just hoping someone has seen this before so they can help me through it.  Any thoughts/help is appreciated.  Here is a couple pictures as to what happens when I try to use it.

First I import a step file.
Then as soon as it loads feature works pops up asking me if I want it to go to work.

I of course click yes, and get this error.  As you can imagine I have no clue where to begin looking based on this error.

Again any help would be appreciated.  Thanks.
