Hi!
I was having problems downloading the latest build myself but figured out a workaround.
The link to version r205.2 is
scirra[dot com]/handlers/downloadrelease.ashx?ID=196
If you increment the ID to 197, you will be able to download the next release which is the current release version r206.
scirra[dot com]/handlers/downloadrelease.ashx?ID=197
Edit: not allowed to post URLs yet. Had to change the address.
