Help with games

[zhenyu21]

Hi people, i am new here and i have got a problem.

I bought my new M55 last week. I tried to download siemens games that i have uploaded myself onto the internet but all did not work.

Can anyone help me and find a solution? I can't get a data cable until the end of the year?

Also, what is the relation between the .jad file and the .jar file?

Thanks a lot
