Trouble Entering Modules in CMP 2.0

[LEAD_WEIGHT]

I get this when entering template but I did not have this problem until I download CMPv2.0 to have my queries enter . I had it in the first CMPv2.0 but download the fix in CMPv2.0 & could not place the addons.
Is it saying that I have module with an identifier of " . " :confused:
"You already have a Module with an identifier of ''. Please select a different identifier."

Are you adding a PHP module? If so, you have to enter an identifier for the module.

What is an "identifier" & I am going into templates not php to add modules when that was the responce but I reinstalled & it is not doing that anymore. Thanks for helping.

simply add a name for the new module "test1" "test2" for example :)
