Fatal error

I want to use this plug-in sooooo badly but this is what happens when I try to activate it.

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

Parse error: syntax error, unexpected ‘[‘ in D:\ASCB2013\2014meeting\wp-content\plugins\litebox\class\litebox.core.php on line 183

Not ignoring the fact that there is a conflict with another extension, but off the top, have you ever seen this problem? Can you help?
