Strange colour with C1 Pro 3.7.7 and 3.7.8 from Canon 1D Mk

Since we installed the update to version 3.7.7 we have been getting strange colour from our Canon 1D Mk2N files - very oversaturated greens - quite different from version 3.7.6:

The same weird colour appears with the latest update, version 3.7.8.

If I reinstall 3.7.6 all is well again. The image above is straight out of camera and has had no adjustments done to it.

At first I thought it was a problem with the ICM profile for the 1DMk2N - but regardless of which version of the program is installed, the ICM profile in Library/Colorsync/Profiles shows the same internal creation date of 7/17/06.

There are no other ICM profiles for the 1D Mk2N anywhere on my system, which is running OS X Tiger (10.4.11).

So I can only assume that the last two updated versions of C1 pro 3.7 are doing something different to my files...

We have a five-user licence for C1 Pro and it's the same on our other Macs.

Any suggestions on how to remedy this would be welcome!!
