Game Error

I'm trying to install new games to my forum and I keep getting this error:

Warning: unpack() [function.unpack]: Invalid format type p in /arcade/functions/tar.php on line 750

Warning: fread() [function.fread]: Length parameter must be greater than 0 in /arcade/functions/tar.php on line 794

Fatal error: Maximum execution time of 30 seconds exceeded in /home/mlguymmj/public_html/forums/arcade/functions/tar.php on line 747

Any ideas how to fix?
