I just did that and got connections increase to 15, but the number of blocks remained. I checked debug.log and found this at the end: ERROR: ConnectInputs() : 68263eacdf mapTransactions prev not found 753aea3823

I had a similar problem running the bitcoin client with a live linux CD a few months ago. It would download x-many (not sure the exact number, but it was a multiple of 50) blocks then stop. However, closing and reopening the client would download another x blocks before stopping again, so it sounds like it may be a different problem. I suspect my issue was related to the timezone setting.
