I think you are correct oe.
onfyre47, the "short tab" or pop-up window you are referring to only shows how much you have spent. If you go to world office>budget analysis you can see that you have $20 million in prospects and $80 million for player payroll. If you then go to world office>franchise payroll analysis, and set it to your team and "all" you can see that you have gone over your budget and are spending $80,043,782. You basically froze yourself from making any moves as the game won't allow anything to happen if you are over budget - I bet you can't even promote players in the minors. All you need to do is transfer in some cash into your player payroll. This will free up your roster moves and allow you to sign internationals. I would suggest just moving $2 million from your prospect budget, which would give you $81 million in payroll. This should be more than enough to sign prospects throughout the season and you'll still have $15.5 prospect to play with.
