Not be able to access grass map

[Seungchan Kim]

Hi, grass users!

I'm a novice in grass world, and got in trouble.
   The trouble is that I could not access any map in the mapset.
   I can see map files (just see), but whenever I was trying to
   access those map files, I got zero values.  Of course, I could
   access those maps before, but from this afternoon I could not
   do anything with the map files. 

Please help me.  I must do something until Thursday.
