Hello,
Thanks for you assistance. I have attached a screen shot of the error message I recvd while uninstalling the program. It is the same error message that I recv when the installation is completed.
That message clearly indicates you that your DLL.XML was already corrupted BEFORE running either the JFK installer or uninstaller.
As the installer/uninstaller says, the file hasn't been touched at all. A formal syntax check is made BEFORE opening it and, in case an error is found, that error message is displayed, alerting that you should first fix the DLL.XML file, before the installation can be successful.
This is an obvious safety check becase, trying to apply modification on an already corrupted file will never work.
So, the reason why JFK stopped working, is that another addon you installed has corrupted your DLL.XML file.
The reson for the corruption is clearly indicated in the error message. Note that, we don't do anything to check the file: we just call the standard official Explorer validation routine, and even the error message itself is coming from IE/Windows so, it's 100% sure your file IS corrupted, and it was it like this before running our installer. In fact, if you try to open that file with Internet Explorer, it will probably give you the same error.
So, either you fix the wrong tag or, if you are not comfortable with hand editing that file, if you simply remove it, the JFK installer will recreate a correct, one from scratch.
