What do you mean by "crash"? Any alarms or errors? If possible, please provide some screenshots.
Which version of lookout?
Is everything working with 1808 in MAX?
Please delete all 1808 related configuration in MAX, and let it find 1808 again. Find devices, and save the .iak file. Then try Lookout. Tell me if you can reproduce the "crash" each time you do this.
