unable to activate licence

A problem occured when contacting licence server… error CS2001

Just wait a while and retry.

Be aware though that you cannot activate a license when using Windows XP.

Many thanks for your repljy… I am using Windows 7 and have tried to activate many times for a 3 week period… C:\Windows\Temp\igxjujlq,0.cs could not be found…Any ideas  ?

I just tried and it seems to be working fine with both Pro and Free License activation.

It wont work for me

Any proxy/firewall or other security application that could be blocking it?
