You can get them GW's launcher.dat on their site & the others have theirs included in their .zip files It could also be your browser, can you check the version? Also do you know what mset is? maybe you have it already installed. You can also install it with rop.bin loader. if you download rxtools it should have an rxinstaller.bin in their mset folder. copy that to your SD's root! & go to "https://dukesrg.github.io/?rxinstaller.bin"I did many times
do you have a copy of launcher.dat. Maybe there is a problem with mine
