[TYPO3-install] error-message right after the installation

[Roelof Wobben]

Hello,

I installed typo with a lot of sweat.
But if i want to go to the backend i get this error-message :

Warning: require(template.php) [function.require]: failed to open stream: No 
such file or directory in /home/tamarawobben.nl/roelof/typo3/index.php on 
line 64

Fatal error: require() [function.require]: Failed opening required 
'template.php' (include_path='.:/usr/local/php5/lib/php') in 
/home/tamarawobben.nl/roelof/typo3/index.php on line 64


What went wrong with the installation and how can i repear it ?

Regards,

Roelof
