I'm experiencing exactly the same issue here too - also on OSX Snow Leopard, fresh install of everything (English though).
If you did not install the patches on the re-installation do so. If not, make sure that you go through all the folders/files in the Preferences folder. When DW was released there was a bug that was in the installer that wrote incorrect permissions on some of the files. If you go through those files you need to make sure your user account has full read/write privileges to the Preferences files/folders as well as some in the Application Support folder in your user Library.
thanks for your reply, but no success yet...
- latest patches are installed
- checked permissions in Preferences and Applciaction support, everything seemed to be fine
- booted from DVD and repaired permissions
Any other ideas?
Exactly the same here - tried everything thilo27 has, and again no luck.
Everything was running fine until I reformatted and reinstalled everything.
After my 4th fresh installation of CS5, I've now managed to fix it. On each occasion, I formatted the drive and did a fresh install of OSX and CS5 - in the first 3 instances, the same problem occured.
This afternoon, I did one thing differently - I didn't sync the MobileMe keychain.
I had previously gone through repairing the keychain, setting a new one etc without success, so I can't be 100% sure that the keychain is to blame for the issue, though it is the only thing I've done differently.
Obviously the issue is solved for me now, but in case it helps anyone else - that's what worked for me.
