I had to reinstall MacOS X Leopard on my MacBook Pro 2.2 Ghz Laptop. It was a clean installation, everything was deleted from the HDD. Now the program doesn't work at all. After startup the interface isn't loaded, and I cannot change between modules (an error occured when attempting to change modules). I reinstalled it already a couple of times and deleted the Adobe Files in the Application Support folder in the Library. Additionally I deleted the Lightroom Package from the Receipts folder, so Lightroom should be entirely off my harddrive.
What can I do? It is a brand new catalog, I tried to make a new one, nothing helps. After I launched Lightroom, I cannot even go into the preferences panel.
I am lost. A lot of other people seem to have this problem, but I just wonder why it worked before? I didn't find a solution and the Adobe Support is just terrible.
