Hi Chris,
the second unfolding was done by holding down the Alt-Tab and clicking on one plane after the other. Then each plane is mmmediately unfolded. But It is not a comfortable process but the result was OK.
I took out also the terrain because it slows down the speed very much. May be PC has not enough power (Intel Celeron 2,8 GHz, 2 Gb memory, Grafic card NVIDIA GeForce 7600 GS 512MB).
Uploading is not possible because the sizes (24 MB / 42 MB) compressed 6,6 MB and 13,5 MB.
May be you have a preferred File Hoster.
