Problem with whole folder

In this year, 2016, probably end of February, the Royals was suddenly can't be played, like some sort of file deletion.
And I thought it was a wrong clicking when I was with my assignment. And I re-installed the game again.
Then, now, at this moment, 12 April 2016, the file was gone again while I was playing MapleRoyals(the game suddenly turn off itself automatically), everything left in the folder was only some sort of trash or .dll file and uninstall.exe
Is there anyway to encounter this problem?
Or is it just me with the problem?

 

Perhaps your anti virus picks it up, try to white list Maple's folder.

 

Actually I didn't use any anti-virus, will firewall perform the same task too?

 

Perhaps it is windows defender.

 

I tried to let mapleroyals access through my firewall, and the problem still comes.
it's the third times now btw, reinstalling it again.. troll..

 

Files don't delete themselves it is your antivirus.

 

Yes, I know that. But is there any suggestion can give to me? ><
tbh, i dont have anitivirus, i only use windows defender and i have let it access through my firewall already...

 

Your firewall is not related to a program you have installed on your computer and it doesn't delete items.

You can use google for a guide on how to make an exception in windows defender or to disable it fully.
Windows defender is an antivirus program

 

Well, feel shame on myself that i can't find a guide that i understand and follow..
Besides, is this a trojan from Mapleroyals,"Trojan:Win32/maptosteal"?
