You still have access to the email address you used when buying PBP?
this is the unpleasant response from Melabs:

Hello
These activation codes from MicroCode Studio are only valid for one year from date of purchase and allow you to install it during that period. There is a free version that comes with our software but if you wish to install the Plus version you will need to log into your account and purchase a "refresh" key at a discounted rate. The discounted rate will not show up unless you log into the account that the full version was purchased under.

Personally I don't like this commercial policy:
after having just purchased the latest update of PBP 3.1.6.4, I discover that I have to purchase the old version of 5.0.0.5 MCSP again...
