[TYPO3-english] Stupid extension installation mistake

[Bill Steele]

I tried to install Seminar Manager extension and stupidly selected the
ignore requirements for oelib. Now the site does not work and reports:

 

Warning:
require_once(/home/yourtypo/public_html/typo3conf/ext/oelib/class.tx_oelib_A
utoloader.php) [function.require-once
<http://www.yourtypo3.com/typo3/mod/tools/em/function.require-once> ]:

Is there anything I can do to recover from this?
