Savegames made with earlier versions of No$ might not be compatable with 2.6.
As a rule of thumb, a jump by 0.1 in the version number more often than not indicates savegame incompatabilities.

Still, you cannot use it. Try removing (copy+delete) the .sav file from your Battery folder and start a new game and see if that loads.

For better or worse...Yes.
