Trouble adding SNMP hosts

[Guest]

I have just installed cacti on Win2000 with IIS. When trying to add my first host to monitor, I receive the following errors:

Warning: An error occurred, Quitting... in c:\inetpub\wwwroot\cacti\include\snmp_functions.php on line 68

Warning: Variable passed to reset() is not an array or object in c:\inetpub\wwwroot\cacti\include\snmp_functions.php on line 71

Warning: Variable passed to key() is not an array or object in c:\inetpub\wwwroot\cacti\include\snmp_functions.php on line 71

Don't know if I did something wrong. I would appreciate any help out there. Thanks.
