Magento 1.7.0 General error: 1005 Can't create table 'db_name.catalog_category_flat_store_1' (errno: 150)'

Question

I'm trying to manually reindex my categories via SSH since it doesn't work in the Magento Admin panel.

Here's what I've done and checked so far from suggestions I found on the net:

• Cleared tmp folder
• Cleared var/locks folder
• Deleted catalog_category_flat entry in db (there was no catalog_category_flat_1)
• Server isn't full - there's 2gb of hosting space left
• User has all access rights for the database
• Used ssh to reindex (php shell/indexer.php --reindex catalog_category_flat)

When I try to reindex via ssh, this is the error I get:

/home/mysitehere/public_html/shell$ php indexer.php --reindex catalog_category_flat
Category Flat Data index process unknown error:
