Quote: Max has 30GB FUP and heavy downloading discouraged during peak. Users reported being disconnected after 40GB
FUP = Fair Usage Policy. This is not a hard cap, but may allow the user some flexibility either by allowing off peak downloading, uploads not included in figures, or the flexibility to go over these caps on occasion, or a mix of any or all of these exceptions. Some FUPs are harsher than others and may in fact be a strict cap.
This may not be your problem but just pointing this out. Another member will probably be along to help you.
