First of all, HI (it is still unknown - whom you address your message to!),
Until you specify 1) receiver; 2) subscription; 3) emulator; 4) server; 5) provide log-file (following the rules of posting logs); 6) specify what is freezing in particular; 7) complete your signature -
DON'T expect ANY answer from us.
I hope, you are a clever enough person to ask your questions in the form you ask them.
Moreover, please, read where you post your messages. The thread is called "Hardware/Upload", the subject of your message is quite different. Either you don't care where to post, or you completely ignore the forum.
regards
