Sudden form creation error after no code change
-
I'm quite new to programming and VB.NET, so Idon't know if this is really obvious. I ran my Rich Text Editor (using Telerik R.A.D. RibbonBar and your own [ExtendedRichTextBox](http://<a href=)), and I got the following error: An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object. Stack trace:

Sorry I did not mention this, but my RibbonBar has disappeared. Kind of. When I click on its area, it shows up in the properties window, but it is just blankon the form. Sorry.
You're probably going to have to remove the RibbonBar from your project, then go through the code files for your form and remove all mention of the RibbonBar. This should let you reopen the form in the Designer. If it does, then you can try to readd the RibbonBar and resetup the properties you had setup for it.
