Avast 2014 on Windows 8.1

[theusername]

I just updated to Windows 8.1 and it removed Avast. I went and installed the latest version and I'm getting lots of issues. For one, I cannot log on to my account (password is correct) It just gives me an error.
Second, I cannot turn on the service or self defense.
Third, I cannot uninstall Avast. Why...

Help me remove this please.
I don't want avast if it won't work, let alone uninstall...

Hi did you upgrade from the preview ?  As it is stated that all programmes will be lost if you do that and it may break the system. 

So remove avast using the uninstall utility

Download Uninstall Utility to your Desktop.
Download the correct version of Avast 
Avast Free
Avast Pro
Avast Internet Security
Avast Premier
Disconnect from the net
Uninstall Avast via control panel

• Run aswClear
• It will offer to reboot to safe mode .. no need to do that

• In the Select Product to Uninstall dropdown choose the version of Avast that is on your system.
  
• Press Uninstall
  
• Once complete reboot your system to Normal Mode
  
• Reinstall Avast

I have similar problem and I didn't update from preview having never installed it previously. Firstly the update removed avast completely, I tried a reinstall of avast and received error message   "Failed to load language dll [ UILlangRes.dll ] then on restart found it had corrupted my register. and locked keyboard out.
Eventually with a restore system manged to get back into windows, manually deleted avast in safe mode cleaned register. Reinstalled avast 9 only to now be in same situation as " Theusername "  and had to once more restore my system to prevent further problems when wanting to restart.

what I did was I upgraded from Windows 8.0 to WIndows 8.1 (from the store upgrade) and everything else works fine except avast. I tried installing the latest Avast 2014 version and I had issues with it not working, then I had to run the uninstaller and it's gone now. If I reinstall I think I will have the same issues won't I?

Difficult to say as I did the upgrade on Friday and everything was still working on completion..  That was from window 8 and Avast 2014 to windows 8.1 and Avast 2014
