Cannot access .dll files

Dimension E510

OS Win XP Pro

 

I have received the following error messages after closing CREATOR DLA (Sonic/Roxio):

 

1. Missing file: C;\ProgramFiles\DellMediaExperience\cmDVDreg.exe

    Cannot access a nesessary file: kcams.dll (DMX.MSI)

 

2. The instruction @ 0x0036ae00 referenced memory @ 0x002sf5d0

    The memory could not be written, click to terminate Mediahub.exe application error

 

3. The instruction @ 12985383 referenced memory @ 0x00000000. The memory could not be "read"

 

4 . Runtime Error!

    Program commonfiles\SonicShared\SonicCentral\Main\Mediahub.exe

    R6025

    Pure Virtual function call

 

Have purchased and used "uniblue Registry Booster 2" which "promised to handle the .dll problems, but it did not work.

 

ANY help would be greatly appreciated!
