I would first suggest attempting to load global settings. This can be found under File > Global Settings > Load
If you’ve previously saved global settings an XML file should be found here under the name you saved it as.
Once you’ve imported these previously saved global settings, you can then load user-defined defaults under DOM settings. This should reset your DOM settings to whatever you defined in a previous instance of GAIN Trader.
If you still cannot load previously saved DOM defaults, then they may have been deleted when you redownloaded the newest version of the platform.
Let me know if this helps,
