Admittedly I did use a .6* beta build. I do want to be clear though about the steps I took when I reverted to build 0.5.14. When I reinstalled 0.5.14 I took the following steps:
- Uninstalled 0.6* via "Programs and Features > Uninstall"
- Manual deletion of "C:\Users\********\AppData\Roaming\calibre"
- Manual deletion of "metadata.db" (Yes, I completely scratched my entire ".db" and started over from the ground up. I wanted to take the opportunity while I have some free time during my summer break to 'clean up' my library, properly tag, etc..)
Point being, this error is occurring after a clean install, with a virgin database. I hope this makes the circumstances a little clearer. Thanks everyone for taking a look at my situation. I hope someone can spot an error in my installation or offer some suggestion.
Thank you. -Abi
