Unable to launch Dedicated Server

Hi looks like i’m the only one with this minor problem. I follow the steps here https://developer.valvesoftware.com/wiki/Rust_Dedicated_Server
I used to run the other servers before but now I actually can’t without the @echo off from my batch file.

-I see people running it with the line: RustDedicated.exe -batchmode +server.hostname “hostname” +server.port 28000 +server.identity “identity” +server.seed 673
Result: my ms dos window stays opened with the directory of the execute file and the line.

-I try using the old line from past rust servers that were working well: @echo off RustDedicated.exe -batchmode -hostname “hostname” -maxplayers 75 -port 28015 -datadir “serverdata/”
-Result: window opens then close. nothing. // I change serverdata to the RustDedicated_Data folder. Resulst: window opens the close too

Please help I don’t get it…
