Error 310 can be a SF server error
or it means ERR_TOO_MANY_REDIRECTS
edit:
Try to rename your cache folder - like here
(if SF closed; after that you need new login)
For more info post your StreamFab.log after delete/once retry
btw: I've no access to Hulu or Peacock

I had v6.1.9.6 and 6.2.0.1 sharing the same cached folder and all was working fine until yesterday. tried multiple versions and all came back with errorcode 310. Then i tried 6.2.0.1, again, without touching the cache folder. And it worked fine. Stopped the queue, tried 6.1.9.6, errorcode 310. Went back to 6.2.0.1 and downloads no problem.
Logical conclusion: Older versions are blocked at the server level. Could be another failed attempt at blocking cracked versions
