Many issues and the thing is still not installed! Started with the Adobe site being extremely slow, had to use a different PC and browser to make the purchase. The install went OK but was horrendously slow - click on a button/answer and it took 2-3 minutes to continue...??? When opened up LR at the end of the install, start getting the "server busy", cannot complete this action messages. Each time just had to wait a minute or so before I could continue. However LR did not complete the upgrade of the catalog, just hung. I eventually cancelled out and tried again.... same server busy messages. Did a quick search and moved the SL directories - no help. Tried an uninstall and reinstall - same problem - cannot get rid of the "server busy" messages.
