yes,perhaps i installed it wrong. I saw previous post saying don't overwrite game folder, I think i just dropped it into the existing game folder
If you installed the patch correctly you won't need to start a new game. At most, you may need to roll-back a bit if you're loading a save directly from the scene. Odds are you installed the patch incorrectly.

radiant-v0.6.2-pc → game → game →

In other words, make sure you're merging the new game folder, which comes with the patch, into the existing one. You should NOT have two 'game' folders. It's also important to make sure you're using a program like 7zip or WinRAR to extract/open the files.
Also, don't worry about individually moving files/folders contained within. Just move/copy the entire 'game' folder, and paste it into the same exact directory where there's already a game folder. IF prompted to overwrite, click yes.
The patch instructions are wrong--don't overwrite the game folder. Merge.
The patch instructions are not wrong. The patch says "overwrite if prompted." This is because some people might be using a version of the game that already has existing images or files from an old patch, or they may have tampered with files (such as copying their old patch.rpy files over). There's also the possibility that they're using an in-game mod of some kind which already has images from the patch.
The instructions say "overwrite if prompted" for this reason. For example, in the "True Edition v0.6.2," some of the images for "c6o" we're replaced/updated with fixed versions from v0.6.1. It's always a good idea to "overwrite" when/if you are asked when merging game folders for the latest edition of the patch... though generally, you won't need to overwrite anything.
