has QuickThoughts fixed their code redemption problem?

Back in April there were a lot of people (me included) who couldn’t redeem QuickThoughts codes because iTunes kept saying they were already redeemed. I emailed them and they said they were working with their voucher distributor to fix the issue and told me to not redeem anything until further notice. They haven’t gotten back to me in like 3 weeks at this point.

Anyone know what’s going on or if it’s OK to redeem codes yet?
