Keep getting a warning message about a map already loaded

[Ergosoft]

Hello Everyone,

I just downloaded a fresh copy of Hercules and everything is up and runing, but the only issue I am having right now is I keep getting a warning message  and I don't kow what's causing it. (I went and looked through out the forum but I could now find anything)

I went and check the following to see if there were any duplicates:

1. map_index.txt file 
   
2. Cache folder 
   
3. maps.conf file
   

Can anyone help me with this issue?

Thanks
