I improved the Auto-Detection of the Download-Button and added Browser capabilities (Back, Forward, Refresh, Navigate) so you can browse to the Download Button if something failed. I also added the possibility to select a downloaded File (instead of pressing the download button), that may be needed if you need to enter the captcha which then forces you to download the file to your PC. In that case just select the downloaded file and it will update from that file.
Updating from all Sites work, but for CurseForge and WoWace you have to expand the little Window which appears and click the Download Button yourself. Waddu then Downloads and expands it automatically.
If you got problems, try running it in Admin-Mode (moving Files from Temp to the WoW Folder in Program Files may give an Error without Admin-Mode).
Thanks, nice to hear that there are still people who like my Updater.
I basically don't take money since that won't give me more time I can spend on it but I don't see any Problems with maintaining it since I myself use this Updater anyway ;)
I will some very simple features (automatic update-check for the Updater itself on startup, one-click updating instead of two-click updating ;)) and then mark it as beta or something. I do think it is pretty solid and working great automatically with all Addon Sites.
