What does that mean? To OP. I just installed it and have no issues. I am also using Win7 64bit, but ult version. The songs actually work fine and seem to match. Some of them I am friends with the musicians and I am asking them to verify and they seem legit. However, always check the comments with anything! Even official songs have bad charting sometimes, like some Queen songs. This is true for any music game because they want to have as minimal downtime as possible (The Collector by NIN from Rock Band rings some bells where the guitar solo is just the keys at the end. Or TBRB where you're playing a cello on guitar for like 4 songs. Don't get me started with things like Project Diva, Guitar Hero, Gitadora (name the instrument version[which Dragon Force here is hilarious to play. I really recommend trying it out if you can just because of the chart making 0 sense sometimes for them]), Sound Voltex, IIDX, DDR, PIU, and many other ones I play) I remember when RS:R came out and I had issues with CDLC then and it crashing but I waited until now to reinstall it and it works fine both offline and online. Even playing 2 guitars works. Why'd you waste $4 for a $2 song? Or why didn't you wait until a steam sale and get the whole thing for 50% off included the req DLC? Does the game run fine without the DLL? You could have a bad install, sometimes happens. Try checking your file verification. I had this happen with Killer Is Dead and Let it Die even after reinstalling both 3 times they didn't work. Do a file verification and it worked fine after that. No clue why their installs are bad but verification helps a lot there. Basically, what all have you tried before just writing the experience off? That's a very important thing to note.
