[TYPO3-dam] Error after installing dam_ttcontent_1.0.1

[Christo Romberg]

Hi!

After I installed dam_ttcontent_1.0.1, i see nothing more in the BE than 
the following error message:

link_edit( 
''.$LANG->sL(t3lib_BEfunc::getItemLabel('tt_content','image'),1).''. '
', 'tt_content', $row['uid']). t3lib_BEfunc::thumbCode ($row, 
'tt_content', 'tx_damttcontent_files', 
$this->doc->backPath,'/typo3/thumbs.php'). '
'; } if ($row['CType'] == 'textpic') { $alreadyRendered = true; 
$damFiles = tx_dam_db::getReferencedFiles('tt_content', $row['uid'], 
'tx_damttcontent_files'); $row['tx_damttcontent_files'] = implode(',', 
$damFiles[files]); $thumbnail = 
''.$LANG->sL(t3lib_BEfunc::getItemLabel('tt_content','image'),1).''. '
'. t3lib_BEfunc::thumbCode($row, 'tt_content', 'tx_damttcontent_files', 
$this->doc->backPath,'/typo3/thumbs.php'); $text = 
$reference->link_edit(''. 
$LANG->sL(t3lib_BEfunc::getItemLabel('tt_content','bodytext'),1). ' 
'.htmlspecialchars(t3lib_div::fixed_lgd_cs(trim(strip_tags($row['bodytext'])),2000)),'tt_content',$row['uid']); 
return '
'.$text.'    '.$thumbnail.'
'.'
'; } } } ?>

Every page looks like this - even the login page displays this error 
message above the login fields.

Main and related software versions:
- TYPO3 v4.0.4
- Windows XP Service Pack 2
- Apache HTTP Server v2.2.3
- PHP v5.1.6
- MySQL v5.0.27
- ImageMagick v6.3.0_Q16,
- FreeType v2.1.10

If anyone has ANY ideas ow to solve this, please post them.

Thanks in advance,
Best Regards
Christo
