Java error when trying to open the client

[paypol 0]

Hi everyone,

 

I'm starting to get into botting and wanted to try out the free version on a Linux (Unbuntu) server that I have. When I run this:

 

paypol@paypol:~/Desktop$ java -jar DBLauncher.jar

I get the following error:

Could not locate proxy file!
