[TYPO3-english] Direct Mail extension and css2inline error

["HocomAdvies [  Wiechert Hooghwinkel]

Hi,

I have a problem with Direct Mail extension. Applied in Typo3 version 6.2.18. Using DM Version 4.1.0 and css2inline extension version 0.1.5

Creating a direct mail message from an internal page goes well and everything looks ok. Than, after sending the test-mail, the received mail has this in the body-text:

Fatal error: require_once(): Failed opening required ‘/var/www/www.**********nl/www/typo3/sysext/cms/tslib/class.tslib_pibase.php’ <http://www.pizzahout.nl/www/typo3/sysext/cms/tslib/class.tslib_pibase.php'>(include_path=‘/var/www/www.**********.nl/www/typo3/contrib/pear/:.:/usr/share/php:/usr/share/pear’ <http://www.pizzahout.nl/www/typo3/contrib/pear/:.:/usr/share/php:/usr/share/pear'>) in /var/www/www.***********.nl/www/typo3conf/ext/css2inline/pi1/class.tx_css2inline_pi1.php <http://www.pizzahout.nl/www/typo3conf/ext/css2inline/pi1/class.tx_css2inline_pi1.php> on line 31

So it looks like something goes wrong with the css2inline extension. In the mentioned file I read:
require_once(PATH_tslib.’class.tslib_pibase.php’);  

PHP Version 5.6.17 . Is this caused by some depreciated stuff in Typo3 6.2 ? And if so, how to solve that? Or is the problem caused by something else? 

Please advice a.s.p. thanks :)
