Problem, please help - Update windows 8 to 8.1 via STORE

Hi there,

I am facing problem in updating my current windows 8 to 8.1 by using STORE

It keeps on showing message: "Something happened and Windows 8.1 couldn't be installed. Please try again. Error code: 0x80070003"

I have tried "Troubleshooting windows update" but still fail.

The error log from "C:\$Windows.~BT\Sources\Panther\setuperr.log" as follows:

2014-02-25 16:06:04, Error                 MOUPG  CSetupHost::DeleteReminderActions(439): Result = 0x80070003
2014-02-25 16:06:04, Error                 MOUPG  CSetupHost::Execute(181): Result = 0x80070003

Can people from microsoft help me on solving this issue.

Thank you and regards.
