i installed lightroom 3 today, and was eager to dive in, but when i imported some photos, they all show up as gray boxes with no image inside.
i've searched this problem, but the only answers i've found tell me to update my graphics card firmware and delete any monitor profiles.
i've updated the firmware and i've even reinstalled lightroom, but everything's still gray.
there are no "?" or "!" in the gray boxes.
i've tried upgrading to the latest version - same thing.
when i select the "web" button at the top right, i can see the photos, but not in other modes.
i'm running xp sp3 with a radeon 6500, 4gb ram.
possibly a clue to the problem - i clicked on a photo in "develop" mode, and i can see a histogram in the top right.
i can pick out red, green, blue, cyan, magenta, etc, but they're all underneath a gray histogram.
You have a corrupt monitor profile. Delete it and then recalibrate your monitor. If you do not have a calibration device then set your monitor profile in the OS's calibration as sRGB, this will fix things temporary but you will require a calibration device to produce consistent colour.
