Delete Posts, Database Level, Feed Import Problem

[pligge]

I have 9.1 set up on a test site to get my feet wet. (with the new security login installed).
Primarily I'm interested in the feed import aspect of Pligg at the moment.
I am non coding and don't speak the language.
However...
In an attempt to empty Pligg of all previous feed imported posts I logged into phpMyAdmin
and emptied the mypliggsitelinks table.
So far so good, all the previous posts are gone and everything else seems intact.
But...
When I then go to import my feeds I get this error message:

Warning: Link::include_once(Smarty.class.php) [function.Link-include-once]: failed to open stream: No such file or directory in /home/.jonquil/john/mypliggsite.com/pligg/libs/link.php on line 170

Warning: Link::include_once() [function.include]: Failed opening 'Smarty.class.php' for inclusion (include_path='.') in /home/.jonquil/john/mypliggsite.com/pligg/libs/link.php on line 170

Fatal error: Class 'Smarty' not found in /home/.jonquil/john/mypliggsite.com/pligg/libs/link.php on line 171

Any suggestions?
Fortunately, DreamHost has a built in Restore Database feature so I'm at least back where I started
but I'd sure like to manage posts at the phpMyAdmin level without harming my feed imports.
Thanks,
pligge
