problem when upgrading windows xp home edition to xp professional

I bought a new computer with windows xp home edition installed on it. I have windows xp professional CD at home. I installed the windows xp professional. When I installed xp professional I have selected the "upgrade" instead of the "install" option as it
should be. It installed xp professional with no problem. Once I finish installing I tried to use my internet that was working on the xp home edition. I was not able to connect. I then tried to make a new connection to re-install my internet. However, some
of the options such as the "dial-up connection" are reccessed (grayed) and are not accessible to select. I did not know what to look for. I took back the computer to the store where I bought it and the technician put a recovery disk of home edition. Then
the dial-up option was accessible in home edition. Then With the hope the problem might be solved I re-installed the Xp professional edition and the dail-up option was again grayed and could not connect to th internet. I put the recovery disk again and I a
m using the home edition now. My computer has visual studio.net, SQL server, visio.net. I am trying to avoid uninstalling all these programs to do the clean install.
Can any one help me how I can upgrade the xp home edition to windows xp professional without facing this internet connection problem?
Your help is very much appreciated.
