I never heard of this happening before. You might want to try to redownload, maybe it's corrupted. Otherwise, be slightly patient. It's been 4 hours since you posted this and it's not like M&B is visited that frequently anymore. If it had been 48 hours, ok, but 4? relax, play a different mod for a while, check back later. The world won't end if you have to wait a day. I'm also going to ask a simple first question: Warband or MB? You'd be amazed at how often that gets mixed up.
