A single user-created toolbox is not opening

[VogtBoat]

Hello,

One of my toolboxes shows no scripts or tools in the toolbox when I click its adjacent plus sign, however when I open the toolbox file up with notepad, all of the content is still inside the " .tbx " file. When I right click this toolbox and go to "properties", nothing happens, and when I select "item description," it says in the following window, "The item's XML contains errors." All of my other toolboxes are working just fine. Might there be a way to do CPR on a toolbox by editing it somehow with notepad or perhaps another tool or update? Why might ArcMap have chosen this toolbox to not open? I have spend tens of hours working on the tools inside this toolbox, so I am still very determined to making it work again.

Here are somethings I have already tried:

• coping and pasting the content out of the " .tbx " file into another new toolbox file
• creating a new windows user
• updating ArcMap
• renaming the toolbox (ArcMap does not allow this)
• deleting the toolbox (ArcMap says "Failed to delete selected objects")

ArcGis 10.1 SP 1

Thanks in advance,

Adam

not much to go on...but in desperation...see

and  A fix for ‘script errors’ when running tools in ArcToolbox | Geographic Information Science informat...‌

and In ArcGIS for Desktop, how do I correct a fatal error resultingin automatic shutdown?‌

for now

Unfortunately, these were not the solutions to the problem. The only thing it could be is that the names of my tools were too long. I learned my lesson.

Thanks Dan
