TYPO3 Core

Nach Installation der Extension : wa_printctrl wurde ich mit folgender Fehlerwarnung aus dem BE rausgeworfen und kann mich nicht mehr einloggen:

Warning: main(/kunden/homepages/37/d13447160/htdocs/sylt-tourismus/tslib/class.tslib_pibase.php): failed to open stream: No such file or directory in/homepages/37/d13447160/htdocs/sylt-tourismus/typo3conf/ext/wa_printctrl/pi1/class.tx_waprintctrl_pi1.php on line 31

Fatal error: main(): Failed opening required '/kunden/homepages/37/d13447160/htdocs/sylt-tourismus/tslib/class.tslib_pibase.php' (include_path='.:/usr/local/lib/php') in/homepages/37/d13447160/htdocs/sylt-tourismus/typo3conf/ext/wa_printctrl/pi1/class.tx_waprintctrl_pi1.php on line 31

Wie kann ich wieder in mein BE ? Gibt es eine Möglichkeit ?
Brauche dringend Hilfe ?
Mfg
