Trying to access dropbox when changing icons in Go Launcher EX

[Ritzckrakr]

So I'm customizing the icons on my new S3, and I'm using Go Launcher EX. I long hold an icon, hit replace, then I'm sent to a screen w/ a list on icons. If I touched the upper right hand corner icon of a picture a new window poped up asking me if i wanted to access dropbox, my sd card, or another service. I could make my choice, then I had to hit, 'just one time' or 'always'. Well, I accidentally hit always while accessing my SD card, and now can't get to my dropbox. When I made this choice, the phone made a quick reference to how I could change my preferences, but I forgot the path.

Any help out there for a simple problem? Thanks.
