Hi,

Does anybody know why I keep getting this msg saying,

"Your file cannot be save. Its name may contain unreadable characters, its name plus path may be too long, or the folder may be read-only, deleted, or otherwise unavailable. Please specify another file name and/or choose a different folder."

I don't have  those problems, but I always got this msg when receiving a file...
Anyone know how to fix it?

Thanks in advance...
