Unfortunately I cannot help you debug your automatic update failure. If after waiting....and waiting....and waiting some more, you decide to give up on your MOD's and wish to just have a functional board that you can re-apply your MOD's to again feel free to follow the following instructions:

Run the /install/database_update.php and then delete the install folder as well as everything in the /cache folder except index.htm & .htaccess.
**If you have customized the default style prosilver or subsilver2, do not upload the /styles folder either, manually update those styles with the code changes package. If you have customized the defaults then uploading the /styles folder will overwrite all your style edits.
Always make a backup of your database as well as the folder you have phpbb installed in before upgrading or making any changes.
