I'm getting tons of errors. I tried some dumb things, and I don't know how to go about fixing it anymore. All I was trying to do was add a column, but then I started trying to do a bunch of onUpgrade stuff, and it caused serious problems. How can I just start a new database with my tables the same? I don't care about losing data from my previous tables. I just want a fresh start. Please help. I need to have this fixed very soon.
