Activate BP Group Documents Fatal Error

Hi, I just tried to activate the bp group documents plugin on my wordpress site and got the following message about a fatal error:

Plugin could not be activated because it triggered a fatal error.

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /hermes/web10/b2537/hy.secondlooks/wordpress/wp-content/plugins/buddypress-group-documents/include/classes.php on line 4

Any help would be appreciated!
