Temporary Internet Content and Cookies not working correctly

I am running Vista with IE7, and I check my Temporary Internet Content and
Cookies regularly. Internet Explorer 7's normal filing procedure is to put
most Content and Cookies in SUBFOLDERS of
C:\Users\Owner\AppData\Local\Microsoft\Windows\Tem porary Internet
Files\Low\Content.IE5, or of
C:\Users\Owner\AppData\Roaming\Microsoft\Windows\C ookies\Low.

Suddenly the system is putting ALL CONTENT in the single folder:
C:\Users\Owner\AppData\Local\Microsoft\Windows\Tem porary Internet Files. It
is putting ALL COOKIES in the single folder:
C:\Users\Owner\AppData\Roaming\Microsoft\Windows\C ookies.

The only change that has occurred is that I had to install some special
software from the company I work with and their tech support told me to
temporarily turn off UAC. After the software installation the had me turn
UAC back on. How do I get internet filing to work correctly again?
