Ok so I got vplaza but am having trouble with it
 

I made all the suitable template mods and uploaded the product as well as customising setings in vplaza and vbux (or vbuz or something) but when i click on plaza main it says your usergroup doesnt have permisions (I am admin) and same for super mod (not tryed any other user-groups) so whats wrong? were can i edit this?

ok here is what you do buddy...
You go into the admincp---->usergroups--->usergroup manager and edit all the permissions from the edit usergroup for administrator,supermod,mods,reg users and all of them. It should work afterwards. but the way, what is the url to your forum?
