ASAP?! You must be joking.
It's not our job to answer someones questions. It's a voluntary action. We're doing it in our spare time. And only if we wish to.
Next thing. You were supposed to read
this before asking your question. How come that you've published your post one hour after sending us an email? Don't you think that it's a little bit disrespectful?
As of your question, I just can tell you that your trouble (most probably) has nothing to do with Mibew itself. You should check your system logs or ask for assistance from system administrators or tech support of your hosting.
