Check that you have successfully connected to your ISP in your usual manner (e.g. Did your dial-up connection successfully connect to your ISP?). This step is independent of whether or not you launch MegaSPEED Web
Accelerator.
Ensure that the ISP you are connected to is, in fact, the one that supplied you with the MegaSPEED Web Accelerator software and connection information. In most cases, you cannot connect to another ISP and use the same MegaSPEED Web Accelerator connection settings.
Verify that the Connection information located in the Settings dialog is the same as that provided to you by your ISP.
If you are running firewall software, make sure that a firewall rule is present that allows access to the Remote Server Port (located in the Advanced Connection Settings dialog)
Try uninstalling MegaSPEED Web Accelerator (Control Panel-->Add/Remove Programs and select MegaSPEED Web Accelerator) and then re-install it.
Contactyour ISP to verify that the MegaSPEED Service is up and running.
