I just installed Revit 2013 earlier in the evening, then managed to evade the prompt to register my license (accidentally closed it then it didn't open again when i restarted) and did THREE HOURS OF WORK before realising that the program was locked in 'viewer mode' and that i could not save the dozens of modifications I have made this evening.
I opened a congruent Revit window and finalised my licensing process, and am able to save in this other window, but my viewer mode program has not updated or recognized this development and I am staring down the barrel of going to sleep having wasted an evening!
Is there something I can do?
I've done the same thing!! Please help me!!! I have just finished a project not realising I was even in "Viewer Mode"! Anyone??????? I don't understand the above comment?
