I am sorry to tell you, but you have no chance to get the player back in re-acution.
This kind of situation has happened before and never an auction has re-opened because the site was down.
As in real life, when you want to get more, you have to risk more. It is a risk to put him for a low price to attract more bidders, but it can also result in a lower than expected result, for whatever reason.
Only in the dark, we succeed!
