CS2 won't save jpg since LR2.7 has been installed

Question

Hi folks,
A few weeks ago I purchased LR 2.7 (and don't regret it for a minute!). Since then my CS2 has developed some funny habits, though, and won't save any  photos as jpg that have first been worked on in LR. The error I get is "Cannot save due to program error". I assume that CS2 (antiques, I know...) is not really compatible with LR 2.7. But at the moment I have to make do with exporting first from LR and then opening it again in CS2 if I need to go on there. Everything works fine that far but after all the work I put into the thing CS2 just won't play. No problem saving as psd file. And I have created a 'workaround' to save my efforts after all, pasting it into a new document in CS2. No problem saving then. But it seems rather strange to me.
I work with an XP PC with loads of space & an external harddisk, a dual core quad processor and 4GB RAM. The original photos are taken in RAW.
Anybody who can give me an idea why my CS2 is having these fits of jealousy since it got competition from LR?
Thanks and grts

Hi Victoria,
Thanks for the very prompt reply!
And yes, I indeed did use the adjustment brush in all the obstinate cases. I
think that I'll go for Jeffrey's for the time being and wait for my purse to
fatten up a bit to get the CS upgrade which I was planning anyway. Thanks a
lot for your help

I'll bet you've used the adjustment brush or graduated filter?  There's a
CS2 bug that falls over that perfectly legitimate metadata.  Your options
are:
>
    •    Upgrade to CS3 or later.  (While we’re on the subject of CS2 and
upgrades, CS5 is the last upgrade that CS2 users can buy at an upgrade
price.  Once CS6 is available, CS2 users will have to pay the full price to
upgrade, as only the previous 3 releases qualify for the discounted upgrade
pricing.)
    •    Check the ‘Minimize Embedded Metadata’ checkbox in the Lightroom
Export dialog, which will strip ALL of the metadata.  It solves the problem,
but leaves you short of any metadata in your files.
    •    Use Jeffrey’s Metadata Wrangler to strip just the problem metadata
from the file, which is by far the best option.

To use Jeffrey’s Metadata Wrangler Export plug-in, you’ll first need to
download it and install the plug-in from
http://regex.info/blog/lightroom-goodies/metadata-wrangler
>
Select the plug-in in the lower left of the Export dialog, and you’ll see
the additional section appear in the main Export options panel — scroll down
if you can’t see them.
>
The only part you need to remove is the ‘crs’ block -– all of the rest of
the metadata can stay.  The ‘crs’ block is the Camera Raw Settings metadata,
better known as the Develop settings, and photos exported with that block
removed will quite happily save as a JPEG, even with Photoshop CS2.
