I often face that problem. Have you connect the folder of your data in ArcCatalog? Well, everytime that problem happens, I always restart my PC and it work normally

Hope this helps

Can you send me a print screen of the error?

Thanks so much Santika I will try

Hello Greta,

Thanks so much for your interesting

The print screen is attached

• The error message doesn't give a lot of information. I suggest you contact your local Esri dealer and send the error report. I'm sorry I couldn't be of much help. Good luck.

Many thanks to you Greta, I did what Santika suggested and it worked
