Dear Rudy,
Thanks for your prompt and kind reply!
I have completed the download. It results in two files:
the first one is named OJJ4500_full_10.exe and it's a 0 kb file
the second one is named OJJ4500_full_10.exe.part and it's a 75.796 kb file that can be downloaded here:
https://dl.dropboxusercontent.com/u/14357953/VARI%20e%20Temporanei/OJJ4500_Full_10.exe.part
When I try to open the .exe file to install the drivers it replies me that I cannot open the file. I've tried with many different programs but they don't work.
I'm currently using a wireless connection.
I will be grateful for any reply or help.
