rebase MI to 0 - 100 & fixed command line opt

Also changed the try/catch option to '-t' as '-c' conflicted with an already-existing option above it causing hilarity to ensue

LOVE the module just added '-n' to rebase MI 0-100 as outlined in the above article (all the way from 2007!)...  Also the '-c' option was used twice so I changed the later one to '-t'
