Cannot init d3d or grf file has problem
- Ragnarok has a maximum resolution of 2048 x 1536. This cannot be changed due to Ragnarok being based off of Direct X7.
- Ensure your monitor's native resolution is set to 2048 x 1536 or lower. On some machines, this requires a computer restart.
- Sometimes its really a resolution problem or just choose your graphic cards and it will work.

My client closes without any warning
-
This is most likely due to a process named core.exe (Warsaw) that identifies Ragnarok as a virus and closes it.
-
To stop Warsaw:
- Use Windows > Run > "services.msc". Then disable all GAS Tecnologia services.
- The service may turn itself back on without your consent,
in which case you'll have to disable it again or look at other ways to fully remove it.
