Issues trying to launch Maplesaga

Hello, just started Maplesaga this few hours ago. I am having issues with launching the program after my Norton security activated 1hr ago. I was playing without having issues when I deactivated my Norton security, but after it reactive from the timer I set 1 hr, it started to detect malware and trojan. I tried the following below as advice

1. Open your Norton application.
2. Click on Settings and then click on Firewall.
3. Click on Program Rules.
4. Click on Add and then select MapleSaga.exe.
5. Click on the drop down and click Allow Always.
6. Click on OK. MapleSaga's launcher should now be ignored.

But after trying to launch my application again i have been getting this.. as attached file

Please adviced!!!
