My guess would be that
1) there wasn't enough money in the account to pay the wages at the time (no big shock)
2) the "new investors" were prepared to put the money in to pay the wages
3) the relationship with the bank is such that they weren't confident that if they paid money into the club's bank account that the bank would then allow the payment out again to go through
On the face of it, now a good sign however as has been explained already it is all just part of the "restructuring" and is nothing to wory about.
