Lance Coffey from Autodesk Technical support directed me to the Revit Clinic Blog on how to unload and Revit Add-in tools you may have.
Here is the link to that blog:
Here are the basic steps on how to unload your Add-in tools.... handy to know...
Fill in the blank #### depending on what year version you are using, ie: If your using Revit 2012 input 2012 where I have shown ####
Firstly Close Revit. Yes I know it sounds stoopid but you'll be surprised how many times I have tried to monkey around with the program while I have it open.....
Then llocate the following folder:
for windows Vista and windows 7: C:\ProgramData\Autodesk\Revit\Addins\####
For Windows XP - C:\Documents and Settings\All Users\Application Data\Autodesk\REVIT\Addins\####
Move the add-in files from the folder above to another location. I created a folder in my add in folder called temp files and dumped the add-in files into that using the cut function.
Start Revit and your add-ins will be disabled.
When testing is complete move the add-in files back into the original folder.
