Like others, I too wonder why you thought you had to change the MB?
Like another poster said, just restore to the point when it did work.
Don't look for the complex solutions but rather try to keep it simple.
ie: today I found out that I couldn't delete files from an external
drive. I spent an hour working on it and realized I had a fat32 drive
and noted most were using NTFS. Since I couldn't figure out my
solution right away, I figured it would be best meanwhile to convert
the drive to NTFS as many others did before me and continue on my
quest for a solution after. Suddenly after I did it, my problem went
away even tho I didn't know this was my solution all along. So the
idea is to try the simple stuff first and see if it works for you.
Even I have to follow my own advice
