.htaccess 500 error

I'm getting a 500 error when i upload the .htaccess file that came with the script for my short url site..

here's the code

RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.* - [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
[B]RewriteRule ^([0-9-a-z-A-Z-_]+)$ goto.php?id=$1 [L][/B]
RewriteRule ^account/(.*)$  $1 [L]

Code (markup):

I removed the highlighted line and it went away...but the script won't function properly without it..

anyone know a quick fix?..My site is hosted with 1and1.com

 

Do you run PHP in suPHP environment?

 

not sure what suphp is, Im on a shared package with 1and1.com i believe it's a sever setting thats causing this 500 error

 

Problem solved..

 

Then let us all know what the problem was
