I got an R4 several years ago and have used it for years. Last year it stopped working so I gave up on it. I was never able to get it to work again after I messed with the files. I have the disc that it came with. The R4 is R4 Revolution for DS (NDSL/NDS) and the disc says the same and says hte site http://www.r4ds.com I have searched walkthroughs, videos, downloaded and installed the software from online, transferred from my disc, and the result is always the same: Loading... Can anyone give me a thorough walkthrough? Thanks!
