Forgive me if this has already been discussed but I haven't been able to find the answer here on the forum and I'm too lazy to search through all the posts.I just purchased BB2017 on hard drive. I need to download and install the up-date/patches. Do I need to download and install each previous build (2017) or just the latest one? In other words, do I need to install 453 then 454 or just 454? Does this also apply to real track and real band up-dates too? Thanks.
