ColorSync stopped working after Lion upgrade.

Question

ColorSync stopped working after Lion upgrade.

I have seen other posts here about apps not working (e.g. dual screens) but the common denominator is that ColorSync has stopped working after the upgarde to Lion. Prior to that, I could use sliders to select tones (i.e. RGB or CMYK) in any application - now it is not there. The ColorSync utility identifies two files with incorrect tag length, and then says it can't repair them as they are locked. In older posts (2009) they say to change the protection on some files under Library/ColorSync ... but even though ColorSync utility says this is where the faulty files are, that directory doesn't exist on my drive.

Is there a way of getting around this problem, or is Apple planning to fix what they broke?

MacBook Air, Mac OS X (10.7)

The RGB/CMYK are working again in my applications - so now I am down to the same issues as other people: that the icc files for LCD and extrenal screen have tags with wrong file length.

Running ColorSync Profile 1st aid, I get:-

/Library/ColorSync/Profiles/Displays/Color LCD-00000610-0000-9CF2-0000-000004273C80.icc

Tag 'cprt': Text tag has an incorrect length.

/Library/ColorSync/Profiles/Displays/Philips 190CW-0000410C-0000-084A-0006-4AB500000000.icc

Tag 'cprt': Text tag has an incorrect length.

Verify done - found 2 bad profiles.

After hitting repair:-

Checking 22 profiles...

/Library/ColorSync/Profiles/Displays/Color LCD-00000610-0000-9CF2-0000-000004273C80.icc

Tag 'cprt': Text tag has an incorrect length.

The file is locked. Could not be fixed.

/Library/ColorSync/Profiles/Displays/Philips 190CW-0000410C-0000-084A-0006-4AB500000000.icc

Tag 'cprt': Text tag has an incorrect length.

The file is locked. Could not be fixed.

Repair done - 0 out of 2 profiles fixed.

Strangely, now a Color Sync directory has appeared under Library.

However, Library/ColorSync/Profiles is empty.

If anyone knows what is happening here, I would appreciate the advice.
