I was trying to create a new project using new Titsnium SDK 1.3.0 but have no success. All the time I receiver an error "Error creating project. Please try again"
No solution but I have the same problem.
Had the same problem. Not sure if it worked once after removing all Titanium related data from Library/Caches and Library/Preferences (this is on Mac OS X) but even if it did, it comes up with this error now again.
I "fixed" it by creating the project with 1.2 and then switched to 1.3 afterwards.
I had this problem, it was all related to my Android install. This thread should help:
as below, creating as 1.2 then switching to 1.3 and saving fixed it.
