I have a couple of questions . 

1 The only problem is the left Navigation bar is missing in Basic? 

2.  Does homebase load as normal?

I know we use to have a KB for this, but I have been unable to find so far. 

Found it!

Look at the Solutions: "Why is the forms bar or Open Forms windows blank or showing out of order."
