1. Run the program.
2. Click (Tools -> Settings) to run the program settings.
3. In the General Tab you will find the “Memory” field. The default value is 800 MB. You can change this to a higher value: 1000 or 1200, so use a value suitable for your memory(Maximum 60% of your memory), then save your settings.
4. Close the program, then restart it to apply the changes.
