hey, upload some info from the debug file in roaming/megacoin folder. if don't know where it is, type %appdata% in windows search
Okay, well most errors I see are like these:
received block d267456af248d33fbfbe46b89934f47cbexxxx040d23a65ca112x85911ff43be
Unable to open file C:\Users\Me\AppData\Roaming\Megacoin\blocks\blk00000.dat
ERROR: CBlock::WriteToDisk() : OpenBlockFile failed
*** Schrijven van blok mislukt
That last line translates to: "Failed to Write Block"
I've also seen this (before I turned timestamps on...):

I've moved the Megacoin directory from %appdata% to another harddisk. So far the Megacoin client has been running from there without an issue. So, tould be an issue on the first disk, though not likely, no hardware errors of any kind, and no other applications suffering. Rather... by moving the directory to another disk, it's also been moved outside the "protected" area of my user account, so I'm thinking it's still something security like. In Windows 7, I think. Too tired to think any further right now. I'll sleep on it
