RegExp issue

Hi!
I'm having some troubles in setting up correctly RegExp to work.
I've created a new "Web Data Entry" and enabled "Enable web browser extension link" and "Use regular expression" in its properties, but when going to that site the extension doesn't find any matching entry.
I've tried filling the "Website" field with a simple RegExp like http(s)://www\.mysite\.com .
If I disable the "Use regular expression" and filling the field with http://www.mysite.com then the extension finds the matching entry and works correctly.
Probably I'm doing something wrong, since in this post the user told that RegExp were working just after implementation.
Anyway I'm using:

RDM Enterprise 10.1.3.0
RDM Chrome Extension 3.0.0.0 (Reinstalled several times)
RDM IE Extension 3.0.2.0 (But it doesn't connects to the RDM installation so I couldn't test on IE)

OS is Windows 8.1 Pro - 64 bit

Just a note, when I tried to install the IE Extension from "Tools -> Extension Manager" it downloaded an exe that run into this error "Unable to locate application file 'RemoteDesktopManagerIESetup.3.0.2.0.msi'." . I had to click on "How to install" and from there download the MSI.

Any advice?


Thanks, best regards.
