Looking into it at the moment, but can also confirm that is a problem that started after a recent AMD driver update - this update seems to be causing issues for some other graphics apps as well.

Thanks Matt appreciate it

Was there a fix about this issue? I can not run old drivers anymore because i am running other software that under performs unless i install recent drivers.

Anyone?? A reply would be nice. Is there any support for this software?

Sorry to have missed your first post. There hasn't been any changes from our end but we do not currently have an AMD GPU to test on. Are you still experiencing the same issue? ReefMaster itself has a software-only fallback for sonar viewing, but the standalone Sonar Viewer does not. If the problem is still current then we will get AMD GPU and try to resolve it, if possible, from our end - please let me know which driver version is affected.

Thanks for the reply Matt. Any driver after the 11/08/2016 update does not work. The software will crash when you choose a file to load. I understand that Reefmaster has an option to avoid using the GPU but i can't afford to spend any more money on this software.
