Can I stop having to fix things please? [rant inside] →[More:]So I have a programming project due next week. I'm using Matlab, which has like a bajillion function libraries ("toolboxes"), and it just so happens that the one function I really really need is not in my computer. So I go get the toolbox from a classmate and drop it into the proper directory for function libraries and set all the right search paths and Matlab even displays the proper help file when I ask for help with this new function and yet when I go to run my stuff Matlab suddenly doesn't want to acknowledge this new function exists. In fact now it's started ignoring the functions I wrote for my previous programming project, despite clearly being able to see them sitting happily in the folder I'm telling it to look in.

I don't know what I'm doing wrong (other than not having included the communications toolbox when I first installed Matlab) and my eyes hurt and it's already taken three days to track down someone with the toolbox I needed and I'm sick of having to fix crap about and on and in my computer just so I can attempt to get started on things I actually need to do and now I just want to curl up somewhere and forget I have to do work at all.

(Last time I had a project in this class, my computer's LCD died.)

This has been your irregularly scheduled online person rant. Thank you.
