[support] acidfree/filemanage module installation problem

I've moved filemanager module and acidfree directory to drupal/modules, and both appear in my modules list.

Problem 1: I did this to set up mysql (as suggested in docs):

david@test:~/howto $ mysql -u acidfree -p acidfree < /var/www/drupal/modules/acidfree/acidfree.mysql Enter password: ERROR 1146 at line 47: Table 'acidfree.variable' doesn't exist

I assume I'm supposed to edit that last line in the acidfree.mysql file, but not sure how.

Problem 2: I activated filemanager (check next to the filemanager name in the modules list and save configs, then gave permissions to authenticated users). When I try to activate acidfree i get this message:

The 'Filemanager' module must be enabled for Acidfree to work. Please download it from the drupal modules site and enable it below.

Any suggestions what I'm doing wrong?

Thanks,

David.
