I just noticed that only my paid Apps are linking to the market. I haven't flashed a new ROM in a few weeks, and all my apps have been linked correctly until today. I have performed the "Market Doctor" function on Titanium Backup and it says that it successfully restored 30 apps. However, when I go into Market, they are not there. I have tried clearing cache as well as installing more apps to see if that somehow resets it. No luck.
