I just had this issue myself. I'm glad I came here first before doing anything drastic, like uninstall and reinstall. I'm in the process of downloading LR 4.1RC, and hope it fixes my problem. I hadn't noticed anything wrong untill this afternoon. None of my previews were displaying. Only thing that I can remember doing since the last time I ran LR4 was install the OnOne LR Presets. I'll report back later as to whether this fixes it.

Well...I installed the LR 4.1RC and it still doesn't display any previews. I even created a new catalog and re-imported all my photos, almost 14k worth, and it still won't display any previews. I'm now having it generate standard previews, and this is taking forever! If this doesn't work, I'll have to seriously think about upgrading the ram in my iMac and start using Apeture!
Anyone else still having problems after installing the update?
