I LOVE my the Stockinhand Calculator mod for reordering that exports a list of what you have and the quantities but it has stopped working properly.

I get this error instead of the list but don't know how to fix it:

Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /home/XXXXXXX/stockinhandcalculator.php on line 23
Stock in hand
Fatal error: Maximum execution time of 60 seconds exceeded in /home/XXXXXXXX/stockinhandcalculator.php on line 66

Is anyone able to help?
