Thanks! I will send a pm with email.
I did not know Epic does not support older version updates. They really should, considering the shaky backwards compatibiity of their releases, which puts your project in danger of disintegrating every time you update. With 4.10 labelled a stability release by them, they basically admittted that all versions before were unstable feature monger versions.
The majority of developer teams stay with one version that works for them for exactly that reason until the end of the project. Updating some project a year worth of work is simply too risky.
