On my RU890, the last file I created with Prontoedit4 is not uploadable to the Remote...

I changed it yesterday, and yesterday on 2.try it went on the Remote.

Today I changed the file again, cause some signs were in the wrong dimension (Pront12 is not showing, so I changes it to Pronto10) and now it failes everytime to upload to RC-Device.

The one I made yesterday has the same behaviour now: Download from RC is possble, uplaod to fails (worked as said yesterday on 2. try).

Any idea what I can do?
