I did some fixing like this long ago:
First -
Backup your file
Then - Open the file as a text file, try to locate the thinckness (it's VERY hard).
Use the find and replace function.
Lats thing - pray really hard
Open the file again, this time as a ASP file (while still praying..).
Good luck
I had to redo the process few times before it worked as I wanted
