I can't change any document

[#1]

When I open and try to change the script on any of the documents on my Server I can´t do it. Apparently it works, but when I open the script again the changes are lost.

Documents accessed through the access point are read-only. You need to open the .qvw document directly with Qlikview Desktop (and with File -> Open, not File -> Open in Server).

I open them just this way. But, suddenly, I’m not been able to change them. Any suggestion?

Thanks in advance
