<h3>What will it cost to upgrade my old copy of MathXpert?</h3>
<p>
If you purchased MathXpert in 2004 or later from Help With Math,  you can 
always download the current version from our website for free,  using the 
serial number that was issued to you at the time of purchase.  We can also assist
you to recover that serial number if you lost it.
</p>

<p>If you purchased MathXpert from another company (prior to 2004 when Help With Math
acquired the rights),  we can't do anything for you.   Please purchase an up-to-date
copy from our website.
