Hello CKOBU,
Thanks a lot for your prompt response. Yes, I first of all formated my USB flash on my laptop with Fat 32 file format. Took it to the psr S670 and uploaded the system Information file in it. Next I took the USB to my laptop where I installed free YEM, plugged it and imported the keyboard system Information into it. Next I then imported some of the expansion packs ( Chinese, western Euro, Indian packs etc) which I downloaded earlier and unpacked (They either have . Ppf, or . Cpf file formats) into the YEM. Next, I selected the pack I wanted to install - marked green. They were not more than the user memory 30 mb. I then saved it on the USB stick after renaming it with .cpi extension format. Next I took the USB to the keyboard to install the pack. I plugged it and it was recognized, I pressed Function- tab - unpack installation- I selected the file and and install then the installation starts. Than after few seconds into the installation, an error message " INSTALLATION IS COMPLETED SOME FILES FAILED TO INSTALL". But after the keyboard restarts, and I go to User expansion, I will find no expansion packs in it. PLEASE WHAT DO I DO. I m stuck on the way now.
Is my keyboard bad? Why is it not responding?
