Try/Catch Logic

Introduce try/catch logic to ensure each step of the process works correctly. Some of this has already happened which mostly stops bad things from happening but some of the errors aren't caught and there are still other places where there is no try/catch logic.

Reopening. Although this has been added, we'll need to pass an error type along with the except. This is required by Pylint and will help catch more errors.
