Parece que o seu Firewall ou Antivírus bloqueia o vimeo! Você pode tentar colocar na lista de permissões, pois o Zonealarm descreve aqui :
- Select Identity Protection|Trusted Sites, then click Add. The Add Trusted Site dialog appears.
- Type the URL of the site (omit http://www), then click OK. After you click OK, ZoneAlarm security software verifies the site address and records the IP address. This process can take several seconds.
- Modify the site permissions as desired. By default, access and clear text password permissions for Custom sites are set to Ask.
