PR Not Starting

A day or so ago, I download PR. After that, it said that it required to Update it. After updating, whenever I try to Launch PR, a window pops up, showing that PR is updating. First, it is at 0%, then suddenly goes to 100%, then the window disappears. This happens once or twice again, really fast. Then, after that, it comes up one last time. This time, it slowly progresses to 16%, after that, the File Count shows 2000+/4000 files done. And it keeps increasing until the window disappears. Even the PR process from the Task Manager is gone.

Never mind. Apparently it didn't update for there was not enough space on my hard disk.
