Is it necessary to download the whole thing over again, or is there a patch that I can apply over the top of HSFX4.1 to bring it up to 5.0 standard? I only just finished downloading 4.1 after a week of frustration and don't much feel like doing it over again!

A clean install is always the best place to start with mods. What you need to do is always keep a copy of the latest stock version of the sim on another drive. Make sure you have added all your skins & users folder etc to it.. even if it is just stock.. or back that stuff up somewhere else but keep a stock version of the latest incarnation of the sim handy somewhere. When an updated mod pack comes out or should you crash or whatever you can just copy that over and add teh mod pack. I have yet to have issues installing any mod pack be it UP, HSFX or even the older ones from AAA on a clean install. Until 4.10 came out I kept a clean stock 4.09... When 4.10 came out I copied that and upgraded it to 4.10 but kept the 4.09 until thre HSFX 4.101 mod pack came out.. then I got rid of the 4.09 and just kept the stock 4.101. If UP ever comes out with a mod pack for 4.101 and I want to try it.. I will just copy my stock and add it.. if I have a HD crash... I will just copy my stock and hit it with HSFX..
