Welcome to the forum.
Can you elaborate on what you mean by "impossible to save and to open file"
Is it opening but slow? Or is it opening , but crashing?, Or is it not opening at all.
Need more detail.
Do you get an error?
What format of file are you trying to save/open?
I agree with Scott not enough info to tell you anything yet.
thanks scott =) my problem is when i save or open the sofware he crashing and a error mess say : runtime error...
(scuze me i'm french, i'm not so good in english)
