Autocad Mechanical 2008 commands not working

hello,

the specific commands for Autocad Mechanical 2008 not working, I get an "unknown command" on my command line.

It all started with this problem:

Issue

During the startup of your Autodesk software, you received the following error message:

Unable to load profile file. Some profile information saved in last session may not be restored.

After you clicked OK to dismiss this error, the program operated very slowly and certain commands did not function properly.

Solution

This error message will occur if the Microsoft® XML parser is not installed or has become corrupted. To resolve this error, use one of the following procedures, depending on your product version:

For AutoCAD 2008-based products and later versions:

1. Exit the affected Autodesk product.

2. Insert the AutoCAD-based product disk into the appropriate drive.

3. Close the installer, if it appears.

4. Browse to and run one of the following files:

For 32-bit operating systems: \support\msxml\msxml6.msi

For 64-bit operating systems: \support\msxml\msxml6_x64.msi

5. Complete the installation by accepting all of the default settings.

6. Click Start menu (Windows) > Run.

7. In the Run dialog box, enter REGSVR32 MSXML6.DLL

8. Click OK.

9. Restart AutoCAD.

i fix it, but the commands still not working.

a screen shot from my computer:

i changed profile to unnamed, but still not working.

You did exactly was is recommended in the red text above right?

What commands aren't working? Or is it still that the profile doesn't load.

The problem you document above is not an easy one to fix. I think the last person to post about a similar problem was told to wipe his hard drive and reload everything.
