RockSim Will Not Allow Me To Add Nosecone

RockSim 9 Will Not Allow Me To Add Nosecone. Anyone else experience this behavior?

1) Start RockSim.
2) Select File->Open.
3) Highlight a design file (*.rkt), click Open.
4) Select 'Rocket design components' Tab.
5) Highlight nosecone.
6) Click Delete Button.
7) Highlight Sustainer.
8) Click 'Nose cone' Button.
9) Information Box is displayed stating 'Unknown database dimension units ("In.").".
10) Click OK.
11) Step9 through step10 is repeated as infinite loop.

I am able to add bodytubes.

Have you tried -

5) Highlight nose cone
6) Click 'Edit'

replace with desired nose cone.

I just started playing with Rocksim. Dang is it addictive! I was having an issue with the "Cluster" feature stating that no cluster that I tried was poosible. I traced the issue to the ID of the MMT being 0.00. Look around at your measurements.

Or try "Edit."
