Can't activate 2.0.4

I was using pie-register version 1. I upgraded to 2.0.4 on my dev site, and was getting lots of PHP Warnings in the logs, and since there was the popup that said that deactivating and activating the plugin would help some problems, I thought maybe that was relevant. But, now it won’t activate because the database tables already exist.

Looks like there are a lot of coding issues in this plugin. I’ll have to see if I can downgrade, or find another plugin, since the old version had issues too, that I had fixed in my local version.
