error for Proteus 7 Professional !

dear friends,
can you let me know what happend for my software.when i open the (.DSN) file and click the circuit ,then that circuit will become empty!when i run the program come out the error(attach file)!the error is
1)nothing to simulate!
2)simulation failed due to partition analysis erroe(s).
pls help me to solut this problem!thank you!

you have to put something in your schematic to actually simulate it well i think you must spend some time to learn using this software.

but i already open the file ,but when i click the circuit ,then will become empty.

@vitorloke plz upload the snapshot of your main proteus screen when it gets "empty"

pls refer the picture!

the first picture has nothing to simulate.

Second picture, if there is HEX file specidied should work

May be u can upload the DSN file.

this is a DSN file.

i dont see any attachment nor any link

i found that some people have the problem as mentioned by u (the disappearing thing) It seems to be related to the TIME ZONE (may be it has something to do with Malaysia)
