Hi there,
I am having a similar problem - I cannot create a new project, as both the 'New' option as well as the 'Import' option on the welcome page are greyed out.
I can open an existing project but when I do, all the Add functions are greyed out so that I cannot add any new fields. Within this existing project, the options to create a new project are also greyed out and therefore non-functional.
I use TMG v.8 with Windows 7.
If anyone would be able to help out, I'd greatly appreciate it.
Cheers
