First of all, the new Package Increment supercedes all of your older licenses. So if you combined your new 2009 Package with your old licenses, it really isn't going to matter.
Now, you need to make sure that your Options file is named adskflex.opt and exists in the same folder as your license .lic file.
Use the TIMEOUTALL 1800 to set a timeout for 30 minutes for all of your licenses.
GROUP should contain users. You need to use GROUP groupname user user user
Definitely add the GROUPCASEINSENSITIVE ON option to ensure that your names are not case sensitive.
You can then INCLUDE the groups for the package and either RESERVE licenses for the group or MAX each group to a specific amount.
Once saved, you will need to reread your license file to put the Options file into effect. Your debug log should show this.
I would recommend reading Chapter 5 of your license manger guide.
