@photomomwife Twitterbar is one of the default sections in PageLines, and not a premium product, so it wasn't specifically paid for as you suggest. Unfortunately, Twitter has decided to retire their first generation feeds. We are aware of it, and working on a solution moving forward. This is not a matter of accessing their javasource.
Twitter now requires a special API and key to make feeds work. Even our premium plugins are affected, as are everyone else's in the WordPress community. There is no guaranty that any plugin or section will continue functioning indefinitely, especially those using a third-party's code. The only solutions are to find an alternative or wait until our developers integrate these changes, which could take a while as they're rather complex. I assure you that every Twitter plugin developer out there is working tirelessly to resolve this issue as quickly as possible.
