This is a question that covers a lot of areas, 1st I have adobe Illustrator 9, and Photoshop6. I plan on upgrading to the new CS series. My Problem lies in that I had bought these durring the Windows 95 and 98 era. I now have Windows XP.
What has happened is all my Beautiful fonts are replaced with ugly faces. I no longer have the adobe type faces that came with adobe Products. I don't know why that happened. 

The next step I was going to do was download the Demo adobe Illustrator CS3. Biggest reason is to see if my typeface problems are to do with the older adobe Product and upgraded Windows XP. 

The next problem I ran into is, in downloading Adobe Illustrator CS3. You have to have 512 MB of ram. I have 512 of ram. I had my computer worked on and got a new hard drive. And it use to show that it had 512 MB of Ram. The trial version won't let me run unless it shows 512 if ran, When I looked up to check out the Computers Ram again to see what it was reading, it read 448 MB of Ram. 

My question is Do you loose ram within your computer, or did someone switch a ram chip durring the Hard Drive repair. With out The computer reading 512 MB of ram, I can't tryout the Adobe Demos to find out what is happening with my Type faces. I seached Adobe/Adobe Type Manager, and I couldn't find it. that is where the typefaces are stored as I read. Obvious I have it somewhere or I wouldn't be able to work with Illustrators typefaces at all.
