Error masg.

hello again,
I uninsulated the latest ver. 4.6 and install instead the 4.5. I thought I will use the old and good ver. after the installation I tried to register and I received a masssage:
ashUlnt
the DDE transaction failed.

so basically I didn’t continue with the registration.
Please help me with this error.
I’m not sure any more if the problem is within my comp. or with the program.

Why did you have to uninstall 4.6 and go back to 4.5?

Will this help? http://forum.avast.com/index.php?topic=2409.0
