Notepad++ : Error with nppcm.dll

Use this freebie program a lot as a simple text editor on Windows XP. I used the right context click plugin which one day suddenly came up with:

""Error creating process: nppcm.dll needs to be in the same directory than notepad++.exe"

Mr Google to the rescue and found the answer.

There is a file in the root of the hard drive called 'Program' - no extension.

Delete this file and all is sweetness and light!

Enjoy!
