Rewrite chart database button
It is not recommended that you use this button at all unless you contact tech support first. This button is used to fix the database error in the early versions of 5 before 22.214.171.124. If you have a later version and your chart databases are working fine, then you should ignore this button. Accidental clicking brings up a warning dialog anyway to protect you from deleting your chart databases. The registry entries for the databases will be wiped, not the databases themselves, but getting access to those databases again would be tricky.
