Omnisphere 2 Cannot Find Steam Folder

When I had originally installed Omnisphere, everything worked great. Then I started to add the updates and everything went haywire. So, I figured that I would just delete everything and go back and reinstall without the updates until I could sort it out. Then, one I reinstalled the program, I get the same error message:
Can not load soundsource '...' in directory 'Core Library'. Try refreshing the index browser.
Now, I have tried everything. After one reinstall, I got an issue that involved a .zmap, and I have no idea what that is or what happened to that. I have seen people on the net with that problem though, which is similar to mine.
I have seen this problem that many people on the net have and no real solution. I called Omnisphere and didn't get a response and I got tired of waiting. I have a legitimate and paid for copy and want this resolved. Some people said that installing the updates will fix the problem, but I still get the same problem even with the updates.
Please help!

Omnisphere 2 Cannot Find Steam Folder Download

Omnisphere 2 cannot find steam folders

Omnisphere No Steam Folder

Once the copy is complete, confirm that both STEAM folders (original and copy) are the same size, then delete the original STEAM folder from the default location. Open Omnisphere and you will be prompted to locate the STEAM folder. Omnisphere Library find - Not a valid STEAM Folder nightmare!

Omnisphere Steam Folder Missing

Hi!
I have installed Omnisphere on my MacBook Pro CoreDuo using an external drive for the library. The installation failed two times, now after having installed it a third time at least the size of the files on the external drive seem to be right. I followed very carefully the instructions in the manual.
When I open Omnisphere in Logic 8 (last update installed) i get a message:
Cannot open Multi /users/hauke/Library/application support/Spectrasonics/Steam/Omnisphere/Defaults/default.mlt_omn
I have downloaded the updates and installed them... no help at all, same mistake.
I have no idea where to look for the mistake. Does anyone have any idea? Any help would be much appreciated!
Thanks in advance,
Hauke
