I see, I'm thinking Internet Explorer got corrupted or there was a recent add-on that is having trouble with Pandora. I will need to log off for the night but will be here at 6AM tomorrow and will check for any emails, I will leave you with these steps for now and try to reply asap tomorrow, thank you:
Please try Firefox and see if it works ok with Pandora, and see if it works ok, if it does, I highly recommend using Firefox it is a much better/faster browser in my opinion and rarely has issues like IE does. You can have both on the computer, and Firefox can import all your IE favorites.
However, if you want to pursue IE further, please try these steps:
Click the Windows Start button, then type internet explorer in the search box, you should see results for it above. Please select Internet Explorer (no add-ons) and see if that lets you back on Pandora without any issues.
Or go to Start > All Programs > Accessories > System Tools > Internet Explorer (no addons)
If that works:
Inside Internet Explorer, Click Tools, and then click Internet Options > Click the Programs tab, and then click Manage add-ons.
Click an add-on in the Name list, and then click Disable > Repeat the previous step until you identify the add-on that is causing the issue.
If Pandora is still not working, click here: http://support.microsoft.com/mats/ie_freezes_or_crashes/
Click the green Run Now button on the page, then download and run the FixIt program. Follow the prompts and see if that resolves your issue, it may ask you to restart.
