same problem - I only get invalid expressions no matter what expressions I put in.. please help

I love this widget, i use it all the time.
but suddenly today it stopped working. I only get invalid expressions... on little things like 1+1 or 35.99/12 its not working :(

Google has changed their response page. The main.js file in the widget needs a minor change to the extractResults function as below. The change is the addition of <h2 class=r> and </h2> in the grepString variable.

function extractResults(googleResponse) {
var grepString = "<td nowrap><h2 class=r><font size=\\+1><b>(.*?) = (.*?)</b></h2></td>";

I can see the need for the main.js change but after applying it it still continues to say invalid expression for anything typed in, and, after closing the widget and reopening, it seems to re-download the js file and wipe out the change. The main.js files I can find on the system are in C:\Documents and Settings\CSAaronk\Local Settings\Application Data\Yahoo\Widget Engine\Main\Google Calculator.widget\Google Calculator.widget\Contents and C:\Documents and Settings\CSAaronk\Local Settings\Applic…ation Data\Yahoo\Widget Engine\Unzipped\Google Calculator.widget\Google Calculator.widget\Contents. I'm using Y!WE version 4.0.2 (build 175). I was thinking the upgrade from version 3.x was the issue. Anybody? More

Using Widget Converter to convert to folder and then editing main.js made it persist. Very awesome useful widget thx
