Spare me the BS, I have been working with computers for decades, and I don't need a lecture from you.
I won't dispute that you've been working with computers for some time, however your posts are extremely inaccurate.
For starters...
Then all the Payware routes, have to be redownloaded and installed again, like S and C, Marias Pass, Roy's Trainz, etc.
Only one of these that you have listed is part of our DLC system. Specifically the S&C pack. As neither the Marias Pass or Roy's Trainz routes are available through the new DLC system, they will not need to be re-downloaded. At this time, the only DLC's that you will need to re-download (if you own them...) will be the 'official' DLC packs (Those that use a '.exe' installer, and a serial number that appear in the 'configure trainz' options).
I have seen posts by people that have installed the patch, that either have or were told post patch to " Oh, just re-install TS12 and start over again", like it's nothing at all.
I only know of a small number of people who have experienced issues that actually require a re-install of Trainz. I think it maybe 5-10 people so far? Note, this is where we have recommended a re-install, or would have recommended a re-install. Out of the total number of people who have downloaded it (and so far, it's only been announced via these forums; so those who have downloaded will have had plenty of opportunity to download), this is a very small number.
Ad to that the warning from 3rd party creators about how their stuff might not work properly anymore, and that is enough for me.
Actually, I've found only a small amount of content in my TS12 that was faulty, at least of content that I actually use. Mind you, most of mine is DLS content, and fairly recent content as well. Those that are faulty should be fixed fairly quickly as part of the DLS clean-up...
Our point is that most of your comments are relatively uninformed assumptions based off comments on the forums, the majority of which we've actually resolved, or are working to resolve. Unless you have installed SP1, you really can't accurately comment on what SP1 actually does.
