I'm not seeing the download/install buttons either. It's probably just a glitch in the matrix, er, I mean, in the endlessly buggy Curse system. If it doesn't resolve itself in the next day or so, I'd suggest reporting your project by clicking the tiny red triangle icon in the bottom right corner of your CurseForge project page, so a file moderator can fix it manually.
On a side note, r20130829230014 is not really a good public versioning scheme... you should use something that non-programmers/mathematicians can actually read without their eyes glazing over. If you really want to use the release date as the version name, just use the year/month/day (drop the hour/minute/second) and put some dashes in it or something.
