[TYPO3-commerce] Fatal error: Class 't3lib_parsehtml_proc'

[Felix Schubert]

Hello List,

after upgrading Typo3 to 4.2.8 and trying to generate an article I got  
the following message:

Fatal error: Class 't3lib_parsehtml_proc' not found in /xxx/typo3/ 
typo3conf/ext/commerce/class.ux_t3lib_parsehtml_proc.php on line 41

Any ideas how to fix it? cause the whole system doesn't work anymore!

Best regards

Felix Schubert
