Opening CC project file on second machine fails

Question

Hello!
I believe I´ve read most or all of the matching topics here but I am still stuck, so here´s my situation.
On my primary Workstation I´ve created a project of medium complexity (150GB, approx. 200 files, 5 sequences).
Here everything is working just fine.
On my laptop I also installed Adobe CC. I copied the whole projects' folder from workstation 1 onto my external HDD and connected it to my laptop.
Opening and cutting works fine here too.
Now, when I save and take the project (project file only) back to workstation 1, here Premiere Pro CC fails to load it up.
The loading bar proceeds to about 75% and then freezes. If I give it some time (10-15 minutes) it finally finishes loading, but Premiere isn't showing any reaction to mouse or keyboard, there are no panels at all visible. Basically it is crashed, allthough that´s not being indicated by the task manager.
I´ve tried all the tips from in here as well as the "usual stuff":
Saving a new project file, nothing.
Deleting preview files, then saving a new file, nothing.
Importing the project into AE and exporting a new project (on my laptop), nope.
Deleting all dynamic linked comps from the old project, saving then taking it to laptop 1, opening and saving it again, taking it back to the workstation, no.
Completely deleting everything Adobe on my workstation 1 and re-installing CC, "great" experience, but to no avail.
I also followed the solution of the similar problem on another thread here in the forums, with unzipping the xml and deleting certain lines of code and so forth, still nothing.
Then I went ahead and installed CC on my second laptop (not at all to be considered a workstation). Here the projects saved on laptop 1 opened just fine (asking for media files of course...).
EDIT:
I forgot to mention that a new and blank project from the laptops opens just fine on the workstation...
So I have to consider that something's wrong with my primary workstation. Right?
Any ideas, anyone?
It´s a fresh installation of Windows 8.1 with 24GB of Ram, GeForce GTX 570, i7 950, WD drives only, Windows on a seperate hybrid disk...
All CC installations are up to date.
Any help would be greatly appreciated as my deadline is on monday...
Thanks!

Answer 1

Try assigning the same drive letter to the laptop's external drive that you have assigned to the media drive on your workstation.  That way, any project saved on the laptop will have the same absolute media file references that the workstation has.
NB: If Task Manager still thinks that Pr is responding by showing you that it's using memory and CPU cycles, then Pr probably hasn't crashed.  It's just busy and taking its sweet time about whatever it's doing.  (Emphasis on "probably")
You mentioned deleting preview files, but you didn't say anything about cleaning your media cache.  Try that.  A good cleaning of your user and Windows temporary files might help.  You should also run chkdsk on your workstation's drives to help you diagnose whether or not hard drive failure is imminent.
