We are getting multiple reports of this problems and are investigating. The licensing team has told us that anti-virus software is corrupting license info, but we remain skeptical.
Please see if the following steps fix the registration issue: - exit all instances of Visual Studio - delete the following directory: c:\Users\<username>\AppData\Roaming\Embarcadero- start Visual Studio - register Visual Assist - restart Visual Studio
Does VA ask you to register again? In the VA About dlg (VAssistX | Help | About Visual Assist), is your serial number displayed?
