When I ran that query after upgrading vB from 3.0.1 to 3.5.0, and upgrading Bookie as well, it reset everyone to 500. Not sure how or why.

That's default behaviour of the Install Code for a fresh install (it can't detect that a 3.0 Version was already installed, so it is a fresh install).

To avoid this, edit the XML and remove/comment out

PHP Code:

if ($installed_version === null)
{
    $db->query_write("UPDATE " . TABLE_PREFIX . "user SET vbookie_cash=500");
    $db->query_write("INSERT INTO " . TABLE_PREFIX . "vbookie_news (news_text,news_type,news_time) VALUES('vBookie installed!','general',".mktime().")");
} 


before you are importing it.
