StatsLab only uses what the game spits out of the database, so if the data isn't in the database anymore, StatsLab loses it. An example of this is box scores. Transactions aren't even exported with the sole exception being trades. Most of that stuff is stuff that OOTP stores in text files.
All that said, it is certainly possible to stand up StatsLab for solo leagues, but you need to set up a web server with PHP/MySQL on it, which requires some technical skill.
