A new twist to my writing life

I started compiling background information for stories into Tiddlywiki for a couple of years now. It was easy to use between home and paying job, and easy to keep updated. Until this week. It works fine at home, but at the paying job, the browser won't let me save any changes.

What I have to work on in every writing project I've got going is background material. So progress has ground to a halt. I don't know the best method to fix it. The files work at home so the problem is probably a security measure they've added at the paying job. So do I find a new way of keeping the information or shop for a laptop that I can bring to work?
