today I made some new stuff and I was going to write it into new pattern...and then I lost everything I've made in that pattern..I've checked system info, it says 0% avaliable...so I've deleted a bunch of patterns that I don't like so much...but nothing...still 0%...and I don't want to delete any of my user patches..dunno what to do, anyone got a clue?? ...they should put smartmedia slot on this machine...like 505...this sux...
