Ok, first thing to do is find those two kernel modules, mbcache.ko and ext2.ko. You might need to become root and then:
Wherever you find mbcache.ko, you'll probably find ext2.ko. Change the directory in those two insmod lines to match the directory where you found the modules. Then try it all again.

Also, the weird spacing in your error messages suggests that there may be something weird happening in the text file you made for the script. Did you use Windows to make the file? You might need to make it again in Linux. It would be best if you used a tablet editor like leafpad to do it.
