ok try uninstalling imgburn, then download the programme again from the imgburn website and install again, the new version should have installed over the old one.
may i ask what the point of that would be?, it's only really relevant when there is something on a disc, in build mode, the disc would need to be empty (no info available as such)
as long as they are genuine taiyo yuden then buy them, its up to you which top surface you want , ie do you want to print on them or not. personally i don't buy other brands that use yuden ink and only buy TYG02 yudens
