The dreaded Error Initializing UI...

I think this may be akin to blue screen of death. Anyway, I after doing lots of work on my form, I was in the Edit Form mode when editing something rather small. I clicked Finish and got an error part of the way through FB saving the code. The error showed up as a DW error (see the attached file). Once this occurred, anytime I attempted to use Edit Form and clicked the edit icon, it would attempt to start but then I'd see the Error Initializing UI, Type Error: groupObj has no properties.

I got a prompt to show the errors and I took a snapshot so you can see them.

I tried deleting the WinDat cache file, uninstalling the extension, then reinstalling it, then firing up DW again and when trying to edit the form, I get the same error. I can click on Edit Design and make a small change and save everything and that works fine. The problem is when I go to Edit the form. Note that I'm using a preset I created that was working fine until all of a sudden it stopped.

I tried creating a new file and using the same preset. After the form was inserted I clicked on edit form and it showed the contents of the form just fine. Then when I clicked Finish, the same error message popped up about a spry widget no longer being present and might not work OK. It seems to have something to do with this:

var Security_info_group_Security_code_Spry = new Spry.Widget.ValidationTextField("Security_info_group_Security_code_Spry", "none",{validateOn:["blur"]});
var Security_info_group_nbsp_Spry = new Spry.Widget.ValidationTextField("Security_info_group_nbsp_Spry", "none",{validateOn:["blur"]});

These are the last two lines of var definitions at the end of the javascript at the end of the page.

Any idea what's causing this? Am I going to have to build my form from scratch to get around this? anything I could edit on my own to fix the problem with the preset?

Note that if I don't use this preset that must have become corrupted somehow, and use a standard FB form type such as simple registration, I can use the Edit form mode just fine without causing the above problems.
