Hello.
Fisrt of all , i'm sorry if the topic has already been disscussed here, 
but I couldn't find anything regarding my problem.
I have just installed the 30 day IAR evalution EW for ARM 
I have a license key and number.
The license manager says that it's a time limited license and 
everything looks OK.
When I try to compile (even the simplest program) I get the following 
message:
"Fatal Error[Cp001]: Copy protection check, No valid license found for 
this product [24] 
"
I'm used to work in the IAR enviroment, I used the EW for TI MSP430.

I wrote an e-mail to IAR but so far no response.
Please help.

Thank you.
