Important News for anyone having issues using the AWSOM Pixgallery image gallery plugin that was downloaded from the http://wordpress.org/extend/plugins/ plugin repository:
The Repository archives the files in a manner that does not correctly name the plugin folder. The plugin folder needs to be called awsompixgallery, but is incorrectly being named awsom-pixgallery. This will prevent the database functions from working properly. To correct this issue deactivate the plugin, rename the folder in your wp-content/plugins folder to awsompixgallery, then reactivate the plugin. This should fix the issue.
I have changed the setup in the repository to compensate for this problem by placing the files in a sub folder with the correct name.
