Can not create or modified new module

Today when I try to create some new slide shows by "save as copy" from the old module, the new modules either cannot be saved or if it does save, the module setting is reset to default and cannot be modified. I have done the same procedure last Friday and it was totally fine. Would like to know if it is due to any limitation of the free version, or if there is any other possible reason? thank you

Hi
Are you using the "slides manager" as source ? it could be that you have too much slides
Remove some slides and try again. There is a limit given by the database, if you want to use many slides, you shall use the source "folder"
