Ok, my guess is not many people had this problem but just in case any one knows anythin I thought I might just ask. When I tried to uploading load my Application (small game) to my phone (SonyEricsson K700i) it failed and I got this message: ///////////////////////////////////////////////////////// Error ================ Install Failed. Internal Method error: point-2 OAFcode=35 EXEcode=11 Application Managementm invalid Java descriptor at download. Execution Envitonment, invalid Java description. ///////////////////////////////////////////////////////// To my amature ears it sounds like something must be wrong with the .jad file. But when I told the SE Device Explorer to transmit using COM10 instead of COM8 everything suddenly started working like it should and my app whas instaled and everything was fine. I tend to get nervous when things suddenly start working without a logicl explenation (because it usualy means the problem will come back at some more critical time) Has this happened to anyone else and in that case do you know what caused it? And what does this COM8 and COM10 mean any way?

I had the same trouble with different jars so I don't thing the trouble is in the jar.

But thanks for asking ^^

(By the way, transmission is working fine on both COM8 and COM10 today)
