Admin page error

Hi,
I have uploaded and activated “Side-content ” plug-in and after that my admin page was crashed and i am getting the following error.

Parse error: parse error, unexpected ‘=’ in c:\appserv\www\evolvablog\wp-admin\admin.php on line 22

Warning: main(ABSPATHwp-admin/includes/dashboard.php): failed to open stream: No such file or directory in c:\appserv\www\evolvablog\wp-admin\index.php on line 5

Fatal error: main(): Failed opening required ‘ABSPATHwp-admin/includes/dashboard.php’ (include_path=’.;c:\php4\pear’) in c:\appserv\www\evolvablog\wp-admin\index.php on line 5

After this am able to enter in to all other pages except admin page. so any one can help me in this regard.
thanks in advance
