From my recent loading/experimentation experiments I think I have discovered the safebox files are now a special abstractmem file/file structure and may require the abstractmem code to be injected back into my restructured edition/branch of PascalCoin to be able to load the safebox properly... (viewing the *.am_safebox files with a file viewer showed some TabstractMem identifier in it, so I base it on that for now and the magic identifier "pascalcoin" seems to be gone ? or perhaps it has a different encoding or a zipped encoding, not sure yet...)
Another solution could be to try and get it from the network, but it probably transfers it in an abstractmem form as well not sure.
A third solution could be to export the data from pascalcoin into a new file format.
