Upgrad 1.0.8->1.1.1: error mantis_config_table exists

[sub4]

hi,

i'm trying to upgrade mantis from version 1.0.8 to 1.1.1, using the mthod described in http://www.mantisbt.org/manual/manual.i ... rading.php.

when i start the upgrade via admin/install.php i get the following error message:

BAD
CREATE TABLE mantis_config_table ( config_id VARCHAR(64) NOT NULL, project_id INTEGER NOT NULL DEFAULT 0, user_id INTEGER NOT NULL DEFAULT 0, access_reqd INTEGER DEFAULT 0, type INTEGER DEFAULT 90, value LONGTEXT NOT NULL, PRIMARY KEY (config_id, project_id, user_id) )TYPE=MyISAM
Table 'mantis_config_table' already exists

the table exists, so the error may be correct. but why does the upgrade skript try to create this table?

what am i doing wrong?
