General ⇒ Tex doesn't build with \usepackage commands

[theiliad2000x]

A year ago I was using tex just fine. Did what I had to with it, uninstalled everything since I didn't think I'd need it again, and now need to come back to it.

I now took a file that worked perfectly fine before uninstall, and found that tex refuses to build it (didn't change a thing in the code). Played around with it, and found that if I remove all the \usepackage lines, it builds everything, but of course completely improperly formatted.

How do I fix this issue? I'd guess it's something to do with packaging updates...

If necessary here is all the code at the beginning of the document:

\documentclass[titlepage]{book}
\usepackage[paperwidth=5.25in,paperheight=8in,margin=.5in]{geometry}
\usepackage{setspace}
\doublespacing
\pagestyle{plain}
\usepackage{ulem}
\setlength{\parindent}{.5cm}
\addvspace{1cm}
\begin{document}
\begin{titlepage}
\pagenumbering{roman}
\vspace*{\fill}
\begingroup
\centering

Thanks for helping in advance!

My hunch in the original post was correct, a simple update of the packages and everything is back to 100%.
