Problem Repairing Database

I tried to get Word Press to check and repair the database. There was a problem with btfr_commentmeta table. I was asked by Word Press to post the problem. At the moment I am unable to login to Word Press. I do not think that is related but if it is and if you know a solution I would be very grateful.

I was told:

btfr_commentmeta: Wrong bytesec: 0- 0- 0 at 18134308; Skipped

this was the output

The btfr_users table is okay.

The btfr_usermeta table is okay.

The btfr_posts table is okay.

The btfr_comments table is okay.

The btfr_links table is okay.

The btfr_options table is okay.

The btfr_terms table is okay.

The btfr_term_taxonomy table is okay.

The btfr_term_relationships table is okay.
