The_Gear, I've got the same issue. I bought the basic Founder option and then upgraded to lifetime via Paypal. I can't access the Founder forum threads or the additional content Vault. Can you help?
Most likely your upgrade is on the Paypal email you used. If you can send me a private message with your Paypal email, I should be able to fix you up. Now under your current username, I didn't find Ashes, so you may need to send me more info in that PM.
