"Go" Fiddler HTTPS certificate issues

Foreigner's question:

I ' m using Fiddler2 (or trying) to capture the SSL traffic for a Windows desktop gadget hitting an HTTPS Web service. It used to work, and then it stopped a couple days ago, always with this error:

---------------------------
Unable to Generate Certificate
---------------------------
Creation of the interception certificate failed.
Makecert.exe returned-1.
Results from C:\Program files\fiddler2\makecert.exe-ss my-n

Sha1
Error:can ' t create the key of the subject (' Joesoft ')
Failed
-------------------------------------------
(I swiped the error from the Google Group for fiddler, although I just posted my own and it should is visible soon).

Have anyone else had this problem and solved it? Is Fiddler just broken?

To find a more practical solution:

The simple fix for me is to install the Fiddler certmaker--http://fiddler2.com/r/?fiddlercertmaker
