You do not have to be connected to the internet for Lightroom to work. If you are at the South Pole, you will be cold.
Please describe the problem in more detail. Also state your version of Lightroom and your operating system.
Thanks for your bitter-sweet reply... I've just signed up to LR & PS 6
In the past I used LR only as an external editor with Aperture (for imports).
I wanted to go cold turkey with Adobe using LR for imports & PS for final editing but find the architecture strange/unintuitive.
Especially for skin blemishes the Aperture 'healing tool' seems to blend much better than the LR:
example: when I added a correction layer for exposure in LR the previous 'healing layer' revealed nasty trackmarks all over the face
Your most recent reply does not address the original question and does not answer the questions I asked.
