There still seems to be an issue when a membership is bought using a different email address from the one the account was originally opened with. The Register dialogue in SD Central allows a different email address for each production registration, including memberships, but if that doesn't match the account address no tokens show up.

Changing the account's email address using the website's account management page successfully transfers all the registered serial codes to the new email... and the TG.net membership serial code then shows up in the list you can see on the website or have sent to you by email. However, the tokens still do not appear, even though the membership is visible.

Changing the account's email address a second time causes the TG.net membership to disappear from the list again. The membership is clearly being tightly bound to the original sale address (whereas it ought to behave like other registration codes and attach to the account and whatever email address the account is using).

Hello, I purchased tokens last night, but nothing appears on my account. I e-mailed support, but have no response yet. I just e-mailed sales, hopefully something would get resolved.

Sorry for the impatience, but I just want to play Sins of a Solar System!   

I am experiencing this issue as well, I see the tokens on stardock central but when I go to use them it shows 0 tokens, any help would be appreciated.

I've got a similar problem. I bought some extra tokens at the weekend from the TotalGaming.net website using PayPal but they never appeared in my Stardock account. When I checked the receipt e-mail carefully, they'd been associated with the e-mail address I use for PayPal which is different from my Stardock one. This worked fine when I bought the first set of tokens, and I used PayPal then too.

Waiting for support to get back to me (it's been 2 days, prod, prod )

Edit - e-mail to sales@stardock.com seems to have sorted it out
