Problem loading showfile

Can the console open show files from its hard drive?  If so, I would compare the software versions of your Nomad and the Ion Classic.  If the console is running on Windows XP, it can only be upgraded to software version 2.9.3.

If you saved as esf in Nomad you should be able to open it on basically all previous Eos version, including 2.something that your old Ion is probably running.

When you say "stop opening showfiles" at what point in the process of loading showfiles do you get stuck? Can you start the Ion into the software? Can you open the browser? in File>Open do you see the USB drive? On the USB drive do you see the showfile? Can you select it? What happens when you double-click or press [Select]?

The Ion is on Windows 7, but it's definitely still on a 2.X (can't remember off the top of my head which one) software version. We know it can update again, but according to my TD, it isn't taking the update. I'm have yet to try it myself. Is it possible we're out of memory? 

Basically, we can see the file, see the USB, everything, but if we try and actually open the file, via clicking or [Select], it does nothing. 

And you're sure that you're using File > Open, rather than File > Merge, right?

If you want to make sure there's enough space on your harddrive, from the shell go to Settings > Maintenance. From here you can first backup your showfiles and pull logfiles. After verifying that you have all needed showfiles successfully backed up on your USB drive you can use the File Manager in Settings > Maintenance to delete unused showfiles or directories.

In the long run you probably want to get in touch with ETC Tech Services to get this sorted out. Your console might need a fresh install of everything. You can find the contacts here. They should be able to get you on the 3.x branch of the Eos software, if indeed your console is a Win 7 generation.
