Architecture / Installation

I tried updating the database and the site to tiki 2, but the problem is still there. I can't access any of the pages that I created. I can only access admin and such on my menu. I decided to also check the mysql database on the server and it came up with 3 warnings:

jmignite_tiki.tiki_pageviews
warning : 12 clients are using or haven't closed the table properly
status : OK

jmignite_tiki.tiki_searchindex
warning : Table is marked as crashed
warning : 1 client is using or hasn't closed the table properly
warning : Found 13100 deleted space in delete link chain. Should be -12048
error : Found 264 deleted rows in delete link chain. Should be 4294967194
error : record delete-link-chain corrupted
error : Corrupt

jmignite_tiki.tiki_stats
error : File './jmignite_tiki/tiki_stats.MYD' not found (Errcode: 2)

When I clicked repair, it fixed everything except the following:
jmignite_tiki.tiki_searchindex
warning : Number of rows changed from 353065 to 352723
status : OK

jmignite_tiki.tiki_stats
error : File './jmignite_tiki/tiki_stats.MYD' not found (Errcode: 2)

Could this possibly be causing the errors on my site and how can I fix this?
