1. Restart computer (if you haven’t already done so).
2. Do you have any kind of pop-up blocker running?
3. What OS are you using? You may just have to “repair” IE.
4. Check for any windows updates, especially if you’re running Windows XP.
5. Try this: Go to Start /Run Type in: regsvr32 urlmon.dll , click “ok”
When you receive the DllRegisterServer in urlmon.dll succeeded message, click OK. Restart computer.
