I've been stuck on this for ages now.... Please help getting "Check why exception occures in the save/load methods."So this "clue" from the mentor does absolutely no good at helping me out. I haven't a clue what to do and I've been reading like crazy to try to figure this out and I all I keep reading everywhere is that it is 1000x easier and safer and better to just use serialization.... please help.
