I currently have some problems with WordPress regarding downloadable files and I have yet no idea how to fix it. I have provided alternative download links for the free downloadable plugins (watch out for it in the comments). If you need to download your TimeHide 1.2 update, please send me an email with your order receipt attached.
Edit April 4th, 2014: Thanks to Ruben Müller, the downloads are working again! Many thanks go out to you! (don’t you dare not to check his website now)
