Not_compatible_with_d7(missing)

Its strange that no one is commenting on this error in such an important "user points" module. Either there is no work done for its improvement or development is limited only for paid customers.

This is used to indicate that this module has not yet been ported to Drupal 7 and is necessary because of a drupal.org bug. Check the issue queue, most have a patch that you can test.

1. Please note that while the Votingpoints module is installed(greyed), it shows "Not_compatible_with_d7" is missing.
2. Please note that I can not disable, uninstall or upload any other module as I receive a message that Votingpoints module needs to be uninstalled. I can not do that even as the box is greyed and cannot be ticked out.

You can look at the .info file for that module and remove the line which says not_compatible_with_d7, that should allow you to remove it. But that's just for getting rid of it, these modules are *not* working.
