user warning: Unknown column 'vtype' in 'field list'

Hello, I'm quite new to Druplal. I installed Video Module following the instractions but now this is what I get when I try to upload a video file (WMV) or even when I try to use URL.

user warning: Unknown column 'vtype' in 'field list' query: INSERT INTO video (vid, nid, vtype, vidfile, size, videox, videoy, video_bitrate, audio_bitrate, audio_sampling_rate, audio_channels, playtime_seconds, disable_multidownload, download_folder, use_play_folder, custom_field_1, custom_field_2, custom_field_3, custom_field_4, custom_field_5, custom_field_6, serialized_data) VALUES (27, 27, 'url', 'http://www.blabla.com/goofy.wmv', 0, 360, 288, 0, 0, 0, '', 0, 1, '', 0, '', '', '', '', '', '', 'N;') in C:\wamp\www\drupal\rtc\includes\database.mysqli.inc on line 151.

What's the problem? Any idea of what am I doing wrong? I'm runnig drupal in on a local server.
Thanks....
