Hi Tell, yes thanks I have the MIB2 Standard and yes I know what a Mac is, I was just quoting the two posts you specifically referred to as important. It's nothing to do with "patience being a virtue", it's about accessibility of information and this thread is very fragmented and difficult to follow because unfortunately moderator has taken ownership of it and updated the first post, or started a new follow-up thread summarizing the correct information.
I will give the relevant steps a try soon and report back.
Basically you go to the end of the thread if it's Mib2... Mib1 fizzled out earlier on, on what you can do yourself to upgrade. Historic nature of the thread means it's all here. People post the workaround elsewhere but people still get in a mess by not backing up and using Macs.
Basically it's easy if you follow the instructions. Mib2 high you seek a retrofitter or cough up. In your case I don't know whether you had Mapcare on your system and whether that has run out then I guess the procedure is much the same. It's never come up.
