ESET endpoint security activation: Can't input symbols

[tadi 0]

My company buys the ESET Endpoint Security and I just want to activite it with the License KEY(4*5set characters with alphabet, symbol and numbers.)

But the License KEY input box refused symbol input (Can not type in). Even I paste the correct Key, the input box would delete symbol automaticly and leave the alphabet and numbers. 

I downloaded the latest ESET version and OS is Windows 7 x64.

Any sugguestion will be welcome.

What symbol do you mean? The license key in the form XXXX-XXXX-XXXX-XXXX-XXXX consists only on letters and number. It doesn't contain any symbol except the hyphen.
