When I start up serum it immediatly gives the error message :error  -534 
and says to contact the support. This is pretty weird and  annoying after buying it and I have installed it correctly, it also loads ofcourse but just crashes.
maybe it's because I had an older demo version before this but I thought I removed everything but there is not more I can think of.
thanks in advance, hope there is a fix forthis cause I wanna use it badly!
