I recently upgraded from Leopard to Snow Leopard, and now I'm having strange issues with a previously working NetExtender.

After debugging a "can't read/execute /etc/ppp/peers" problem (since /etc/ppp didn't exist) and following the advice on the Apple support forums (I tried a clean install, and sudo chmod u+s /usr/sbin/pppd had no effect), I'm getting this error:

Connected.
Logging in...
Login successful.
Using SSL Encryption Cipher 'DHE-RSA-AES256-SHA'
Using new PPP frame encoding mechanism
SSL-VPN logging out...
FATAL: An error was detected in processing the options given, such as two mutually exclusive options being used. (2)
SSL-VPN connection is terminated.

Thanks for any help.
