They've changed the format the mails are saved in so the two systems are no longe compatible - and because the mails are on two different machines I can't just convert them across either with a simple upgrade. Nor have I been able to convert them to Mozilla Thunderbird on the new machine so am now downloading a 'trial' version of the 2007 package onto the portable harddrive so I can then transfer that to the old computer and load it up (the old PC is no longer connected to the web so I can't do it straight onto it) then do a transfer internally between the programmes. Then go into the operating files and save the mails in the correct format the new programme can read. Then save THEM onto the portable harddrive and bring them across to be inputted into the actual full programme I have running on the new machine.
I may leave the programme downloading and go to bed (or atleast read). I almost went to bed at 9.30 this evening because of various tiredness and no one being home to talk to but decided to try and fix the email (which I've been actively trying to do all afternoon!).
Hopefully this last attempt will prove successful.
I'll know more in the monring...
