First of all thanks for the excellent work the Kloxo-MR, really appreciate it

Let me get straight to the point.
I have been using kloxo on my VPS for over 2yrs, had a fresh install on my vps due to data center migration by my host around an yr ago. Now, for past some months I haven't been able to open up kloxo, not sure what the problem is, my host added some security patch on my system + did some back end software upgrades, the problem was noted after that.
This didn't affect any of my sites though, they have been working great, no issues what so ever. The only prob is I can't access kloxo, I get blank page when I try to get to the login page, when I can't get login page, I can't even logon, so I'm at least in a way relieved no one can hack into my kloxo using login access, lol!!!
I have heard about this serious exploit on kloxo, so I'm thinking to upgrade to kloxo-MR. I would like to know how to do that ?
My HDD is huge, really huge .. over 90GB data stored, as I have an image host script running on it, along with 3 WP blogs. I don't wanna loose data & I can't go through hours of interruption, as it would affect the reputation of my imagehosting site, which may not be worse than over all interruption, so I'm looking for a safe way to upgrade kloxo-MR from my present state, where I can't even open kloxo.
Just in case needed - I am on Cent OS 5.x, VPS with 2gb ram, 3gb burst
