Forum mySQL tables corrupt "in use"

[محروم.كوم]

I have this problem this morning as I moved to a new host and found out that the problem is exactly the same like this guy had http://www.wjunction.com/showthread.php?t=27564

I have 4 tables which are corrupted

Quote:
searchcore
searchgroup
searchlog
tag
tagcontent

HOw to fix them plz help..I tried to repair the tables in php myadmin but still it shows table corrupted.


Incorrect information in file: tagcontent.frm
Incorrect information in file: tag.frm'
Incorrect information in file: searchlog.frm
Incorrect information in file: searchgroup.frm
Incorrect information in file: searchcore

These tables cannot be repaired in anyway. in phpmyadmin or vbulletin admincp maintenance

I would like to know what caused this?
my dev forum at the new host is a very basic vb403 installation. no mods etc. __DEFINE_LIKE_SHARE__
