All my Fonts have changed

[puzzler]

A very strange thing has suddenly happened, all my in menu Fonts have changed into some font that's very difficult to read, does anyone know how I can change them back to the default?

Two possibilities. One, you have switched on the 3D menu text option in the options screen (Shift-O), in which case all you need to do is switch it off again (or vice versa). Two, you have ejected from your ship inside a station and are suffering the text-doubling problem described in the Known Issues thread, in which case you need to revert to the last savegame before you did this.

Thanks for your reply, but no it's neither of those options.
The last thing I did was purchase the MK3 trade thingy and then all the fonts changed to a different one but unfortunately it's not a very good one and is smaller and very hard to read.
