>>A CTP is by definition something that yu should always install in a test environment.

Yes, I know. I did not install it myself. I was just saying some others who had done so had experienced some problems.

>>I saw many succesful installations of the SP 2 CTP (the Sedna CTP didn't break anything).

Yes, now that you mention it, I believe it was the SP 2 CTP and not the Sedna CTP. I'm not really interested in installing the SP 2 CTP, but thanks for your offer to help. I was interested in installing the Sedna CTP and, as you've reminded me, that wasn't the CTP that broke things. Maybe I'll actually find time to install it. <g>
