I had exactly the same problem... and I've found a solution...
you have to follow this steps:
1. open windows\system32 folder from the other operating system
2. delete "wpa.dbl" file
3. rename "wpa.bak" file into "wpa.dbl"
4. run your causing-problems operating system
Vuala... It works in my case
Worked for me. Thanks for posting
