G'Day Guys,
I sent Tim 3 emails about still have not received a reply.
So I just paid for the plans again and this time they downloaded without issue.
The Zip file is 4.9mb and has 3 files, PDF , JPG and the sketchup file. just for anyone who needs it
The first time I tried to download the zip at work, so my work firewall/antivirus must have done something.
Thanks to everyone who replied.
