196	<p>It appears that you have installed FeedWordPress
197	<?php echo FEEDWORDPRESS_VERSION; ?> as an upgrade to an existing installation of
198	FeedWordPress. That's no problem, but you will need to take a minute out first
199	to upgrade your database: some necessary changes in how the software keeps
200	track of posts and feeds will cause problems such as duplicate posts and broken
201	templates if we were to continue without the upgrade.</p>
202
203	<p>Note that most of FeedWordPress's functionality is temporarily disabled
204	until we have successfully completed the upgrade. Everything should begin
205	working as normal again once the upgrade is complete. There's extraordinarily
206	little chance of any damage as the result of the upgrade, but if you're paranoid
207	like me you may want to back up your database before you proceed.</p>
208
209	<p>This may take several minutes for a large installation.</p>
