ok first off this is a really shitty launcher, i feel bad for whoever uses this, this is easily decompilable and crackable, i can literally get access to your database just from using this shitty launcher, C# should never be used for launchers as it's the most shittiest language ever and we can just decompile it with ease, also never trust the client for SQL connections...
really?????
just fyi, deleting cache folder is useless in 99% of the problems.
there should be more, i just cant be bothered to look at this horrible piece of shit code
