Error no. 145

Can't open file: 'yabbse_topics.MYI'. (errno: 145)
File: /home/saleh/public_html/mugenswa/forum/Sources/BoardIndex.php
Line: 152

I saw this message three times in my forum .. is it something in the server service or a common error in MySQL DBs ?
and how can I fix it ?

go to phpMyAdmin and run this query: REPAIR TABLE yabbse_topics;
