I am just beginning to use InstantWP, but am having some issues. I tried updating the WordPress version by logging into the admin panel and clicking to update. Both tries failed. I also was able to install the theme I'm using, but when I make changes to the theme settings (like background, colors, etc), nothing shows. There is a warning at the top of the page saying that it wasn't installed correctly as well. I'm using the UDesign theme from Themeforest.
