Okei, I solved that. I just proceed from phase 3 to 4 and all went well. I haven't noticed that system is faster but there's now more space to install applications. If I upgrade to Sardine will those installed applications be there also and will they work on Sardine? Does Sardine mean I have to install all once again? Now I'm thinking upgrading to Sardine, before this I didn't have enough courage to even think about upgrading.

Thank you Millhouse for these instructions! Great job.
