not able to load XML files

Sir,
I am not able to load XML file , an error comes " Error transforming XML data ". Please tell me the solution as soon as possible .
Thank you .

Please provide steps to get this error.

Steps :
1. After creating subsystems , catalogs , enumerations , the next step is to load XML Data version.
2. Then next step is to browse XML file such as 01-ContactTypes.xml , 02-FriendStatuses.xml and etc.
3. In this step first three files loaded successfully but the rest show as error i.e  " Error transforming XML data "

Please tell me the solution as soon as possible .
Thank you .

Does the advice from the topic help? Files from what version pack do you use?

version is 8.3

I am doing exactly same steps from Hello 1C.pdf . I don't why this error is coming .

Make sure catalog names and attribute names are equal to the XML file attribute names. I checked files till 04-EventStatuses, all of them are imported. I checked files from this pack.
