Adobe Indesign Standard CS5.5

Hi 

I have a serial-number for product(Adobe Indeisgn Standard CS5.5-chinese traditional language), it is volume licensing, under CLP Licensing Program.

Recently i had reformat my desktop and re-install this product (Adobe Indeisgn Standard CS5.5).

It will prompt me a window(something like countdown 30days) for activation.

If i choose the first option- activate via internet, it will failed and keep saying my desktop no internet access.(*i had verify that my network is fine, nothing block to adobe website at host file, my dekstop is on workgroup,not domain).

then if i choose the second option, it request to key-in serial-number. i re-key-in the same serial-number which i use to install this product. it said the serial-number not valid for this package. 

Please help.

Thanks you in advance.
