I\'ve looked around and havn\'t found anything about this so if somebody knows whats wrong or can help at all please let me know

9:58pm +10GMT (australia) is the current time...... I was in planeshift about an hour or so ago when the server guy poped up and said the server was going down to update and that the clients would also need updating.
All standard happening, yes.... However when the server came back online and I went to update, I got this error when it tried to update the updater.
\"File Copy Error
Couldn\'t copy file cspngimg.dll!
The process cannot access the file because it is being used by another process (32)
RETRY - CANCEL\"
NOTE: that this error pops up again and again for several different files.
So that do I do... I start looking through my processes lol, hoping to find something obvious..... nothing.
I restared my system incase something had gotten lodged in memory or somesuch, but still no luck... Same thing happens every time.
Hope someone can shed some light on this.
Methos.
