[PD] textfile read failed winxp

[brandt at subnet.at]

hi list

after searching the archives without any success i wanted to ask, if  
anybody has an idea to handle following problem:

i stored 43 files named preset(1).txt in a folder named  
D:/Mkoffa_root/presets/. with makefilename  
D:/Mkoffa_root/presets/preset%d.txt i open the file by number. it  
works but after a while pd is complaining that for can´t open....read  
failed and it never opens one of the files again. after that even  
openpanel and trying to open by hand doesn´t open the file abymore.

any help?
