Can't 'resume' royal flush campaign

[the_bengine 0]

Hi guys,

Me again

I've just been trying to load up my progress in Royal Flush and, every time i do, Arma crashes and i get this "OK button" message box:

Cannot load: 'blah blah blah

Profiles\MyProfile\Saved\Campaigns\Merc\continue.ArmaSave'

The game runs fine if i revert the mission back to the start but it can't resume it.

Any suggestions?

thanks in advance.
