Hey Bethany... so sorry it has been rough but things can only get better eh ?!
I have occasionally had a No Delivery and rather than change the whole set I usually just do a Prime->Rewind and then a Manual Prime to reset the system... seems to work for me.
I work with computers too and know just what you mean... when you are in a hurry the darn things just seem to get slower and slower
This might cheer you up:
