Hello I'm upgrading. I've downloaded the new package. Do I just ftp it to my amember folder with all the existing files or do I have to be cleverer than that? Do I have to delete the old amember files / folders and start again? Also I noticed zipped folders in the new installation - do I have to unzip them first? Are there any instructions anywhere to tell me what to do?! Thanks
Those instructions are for upgrading V4-xx to V4-yy. You need to follow http://www.amember.com/docs/Migration_from_legacy_aMember_Pro_v3 instructions. When you upgrade to upload the new V4 files to a new directory. Get it working properly and carry out any customisation etc. This way you can upgrade with minimum disruption to your current working site.
