With a long line of text like your field_13_id data, Phorum renders the thread unreadably, so I started a new thread for this topic.
The table structure is absurd. I'd immediately start looking for a tool that doesn't rely on such monstrosities.
Upgrading the table to Barracuda may be the only viable solution (see the thread a short distance below] yours on the same error). You may have to do tricks to accomplish it, eg break the table into parts, upgrade the parts to Barracuda, then re-assemble the table.
