If you are an Avast! User like me.. you can simply follow these few steps and it SHOULD fix your client crashes...
1.) Locate your patcher location... for me it was under:
C:\Program Files (x86)\Gravity\DragonSaga\Patcher.exe
2.) Open your Avast! virus protection interface
3.) locate your sandbox :
Under Additional Protection -> Auto Sandbox-> Settings...
4.) Copy and paste the patcher location into exceptions section under auto sand box.
5.) Go to the top right corner of the interface, and click the Wrench Icon : SETTINGS.
6.) Find the Exclusions tab: once again, copy and paste your patcher location into the exclusions section.
If your client still won't work it is recommend you do this step :
Locate your Avast! System icon, now right click it
1.) Click Avast! Shields control
2.) Disable your shields for 10 minutes.
3.) Restart your client.
IT IS IMPORTANT TO UNDERSTAND : When shields are down, you should probably stay away from browsing the internet for awhile. ONLY go to trusted sites, but please remember even Facebook can give you a virus...
I hope this fixes most of the Avast! user's problems with Client crashes,
Happy Gaming!
