Kit launch error LS-0013

I haven’t seen any posts on this yet, but after using the kit for 2 weeks it suddenly will not open and gives the error LS-0013. It says to verify installation.
I did it twice with the same result. I reinstalled the kit with the same result. I just got started modding and this is really discouraging please help.

Just to add. After reinstalling the kit an update appeared (this is the second reinstall). The install verified the update but problem persisted.
I did find out that now I can launch the kit directly from the batch file (Should have tried that earlier :p). I don’t think that it worked before though I know that was the way to
do it when steam had the kit.

I had the same problem.
Try launching as Administrator; that fixed it for me.
