RoleManager breaks in 2.0.4

Hi,

UPDATE: I did a fresh install and now role-manager works fine. Maybe somebody knows why the errors occour?

i have ben working with RedAlt’s RoleManager-Plugin in WP 2.0.2 and everything was fine.
Now I updated to 2.0.4 (ger) and nothing work anymore.

FireBug tells me the following Error:

missing ; before statement [tw-sack.js (line 63)]
<b>Fatal error</b>: Call to a member function add_cap() on a non-object in <b>C:\xampp\xampp\htdocs\scoutpress-dpsg-langerwehe\wp-content\plugins\role-manager\role-manager.php</b> on line <b>330</b>

The line 63 in tw-sack.js says

this.runResponse = function(){
62 eval(this.response);
63 }

Does anybody know whats wrong with role-editing and how to solve it?

Thanks
