Rocksim V9 Project Viewing Problem, help please:)

I have been working several hours on a project with Rocksim V9. Don't know if I hit a key or something but I can't view the rocket any longer in the lower box. I do see a blue dot in the middle of the box about the size of a period.
I've tried reloading the file, saving the file under different name and reloading it, but nothing works. All the parts are under the design components section, just no 2d, 3d or any other picture of the project.

The screen shows the specs of the rocket in top right corner. Just can't view the rocket drawings.

Let me add that other projects load up and work fine. Just not this one

Thank you!

If no one replies here, you can try contacting Apogee directly (they have a browser based chat window) and describe your problem to them. They may be able to help, but it looks like they don't open until 9am Mountain Time on Monday.

Will do, done redone all the work but still what to know what happen and the way out
Thanks

I got with Tim and here is a quote from his reply: "I do not understand how the design could just disappear like that. I've never seen that happen before. I would just assume that the design file was corrupted somehow."
I actually sent him the Rocksim file itself to. I agree with him, I have never had my build project rocket just disappear, only a small period in the middle of the screen. I printed out a copy of the parts, templates, etc. & rebuilt it again in Rocksim. I'm not new to Rocksim, been using it from the early 2000's. I've worked with V7-9. I'll attach the Rocksim file just to see if anyone can restore the image of the rocket in the lower box and if you do, please share with us how you did it.

Thank you!

I started deleting things until the image reappeared. Deleting a single body tube causes the image to reappear. The one I deleted was:
Sustainer->Titan IIIe Main Air Frame -> (2nd) pod -> SRB Lower Body Tube -> pod -> Body Tube

Also, deleting that component changes the Span Diameter from 5000 inches to a more reasonable 4.92 inches.

The pod containing the deleted body tube has a radial distance of -2500 inches.

Also, the other "SRB Lower Body Tube" does not have this nested "far-out" pod.

Thank you very much, learned a lot from your post. I have never had this happen to me before, losing a diagram. Not sure how that happen, must have bumped a key or something while working on that area and didn't notice that. The Radial distance should have been 0.1250 for that part. Never knew that a incorrect entry would cause the main diagram to disappear or reduce itself to a very small dot on the screen.
Thank you once again!
