I'm trying to update my PD6 to v7 but all the downloaded dmg files are corrupted and can't be installed. The first download was 163 Mo, the second 242 Mo and now I'm blocked due to "not more than 5 downloads".
I had exactly the same problem with multiple download attempts dropping out before they completed. Thankfully it completed on the forth. I suspect that it is a problem their end that is dropping the connection. They also should not count a download until it completes in its entirity.
