I had a look around but didn't find an answer, and searcg fnction is down.

When I try changing themes, it keeps saying 'error creating log file, exiting'.

how can i stop this from hapenning?

Found out the problem. I had to end task a file, named something like ns59.tmp or ns5C.tmp. As soon as I end task the file it ran perfectly. Everytime I change a theme or something in Litestep I have to end task a file similar to those.
