Edit: Well...damn. I can't see the transaction history in the old league. I was going to go through and record who swapped what picks. Garbage Goal, can you access that?
You cannot access this league because it is a Premium league and there is still an outstanding balance owing. You, or anyone in the league can pay for part or all of the amount outstanding. Click here to get to the page where payment can be made. Alternatively, the Commissioner can remove the premium features being used via League Setup and then downgrade the league to a Standard league, which is free.
I can't. Even if I could it would take a while since I have to go to the library every time I wanna use the computer. My suggestion is just roll with it. Sorry.
I also recommend everyone chipping in for the premium league if you can. If the league is the same size as before then it essentially converts from sixty out of Beef's pocket to five out of everyone's. much smaller, marginal amount.
On second thought with premium stays you got priority for customer support. Send in a ticket or whatever explaining the situation. They might be able to transfer the pick status' over between leagues. Or something.
