Error code bX-4d29hg - what to do

I had earlier wrote about Error code bX-jdokxi - what to do. I got another error message when I tried to change the template of Isaac Low's blog. The error code was bX4d29hg. I did the same thing as for Error code bX-jdokxi. I backed up Gadgets (Page Elements). (I didn't backup template because the blog was relatively new, but it is always a good idea to backup template whenever you are making changes to the template. I then deleted the all the gadgets. After deleting all the gadgets I had no problem changing to the 4 column Minima template.
