Help with reinstalling Photoshop CS5 after CS3 disaster

Help!!

I have been using PS CS3 and CS5 for years.  2 days ago I got a notice on CS3 that my software wouldn't work in 5 days if I didn't re-register the product, something about a server crash.  So I did exactly what they asked for, and it wouldn't install.  After several hours of frustration I got the Chat help.  The technician asked me to delete a subfolder in my C drive Adobe folder.

Not only did this not work, but it proceeded to make CS5 - also on my computer - nonfunctional.  Another 3 chat sessions, and they are telling me to contact them after 5-7 business days.

SAY WHAT??!?

So I uninstalled and reinstalled CS5, which was in 2 parts from the download menu.  An "English Universal" and an English International" part.  The .exe file opened no problem, the .7z file seemed to have trouble opening and wanted to know what app I wanted to use to open it.  Strange.  But it did unzip, in a folder on my desktop.  When I opened the installer it asked for my product license.  I put it in, and it acknowleged it as a valid license. So when I hit "Next" it opened another window that said although it was a valid license number, it wasn't for CS5.  Even though on my product page on the Adobe site it says it is for PS extended, CS5.  No mistake.

So now I am stuck.  I tried to use a restore point on my computer from only three days ago, and although the PS icons are back of course they won't launch.  it gives me an error box saying to uninstall and reinstall the program, and if it doesn;'t work to go to customer support and tell them about an "Error 1" message. Great - they don't want to let me use the on-line Chat support for 5-7 days.  I tried to reinstall and do what the FAQ section of this Forum suggested, to go to the installer box and Ctrl/Shift double click to get a "code" to revalidate my product code.  But I need to read it to an Adobe representative and enter another code they are supposed to give to fix the product registration number problem.

How do I get around this??  By doing what Adobe asked for CS3, their techs have now left me without CS3 AND CS5. And they don't want  me to ask them for help on the on-line chat for 5-7 business days, according to the chat transcript.  Is there a different way around this problem??  I took several screen shots of the installer glitches, if that helps and will try to upload them here.

Thanks to any and all help on this problem.  If there is another way to get tech help from Adobe, I am all ears.  I feel insulted that after spending $750 for PS and then another $140 in upgrades from CS3 to CS5 that they won't help me after trying to do what they asked about re-registering CS3 and all the problems it created.
