Fresh Install Activation Errors: PDOException: SQLSTATE[HY000] Error writing file

Hello all,
We just did a fresh install of Backup and Migrate. Looks like a fantastic module. We had to manually upload as there was some sort of permissions based issue preventing the auto install from the Modules control panel. Upon module upload, and trying to activate the new module, we're presented with the following error string. The module is then checkmarked as in it was activated, however, we do not see the module appearing in Configuration>System>Backup and Migrate. It seems something is preventing the module from completely activating, due to the error.

Can anyone make any sense of this? Is it a permissions issue, and if so, I'm wondering what file exactly.

PDOException: SQLSTATE[HY000]: General error: 3 Error writing file './ourcompanyinc/main_backup_migrate_profiles.frm' (Errcode: 28): CREATE TABLE {backup_migrate_profiles} ( `profile_id` INT unsigned NOT NULL auto_increment COMMENT 'Primary ID field for the table.

Thank you!
