problem upgrade 5.1.9 to 5.2.0 Patch Level 2

[origami]

Hello,
I have already upgraded to 5.1.9 before proceeding carefree and then I did not update to latest version 5.2 at present .
then I decided since Thursday to upgrade to 5.2.0 Patch Level 2, same operation as the previous version but :



Step number 1 to number 5 carefree but this one is in step number 6 which poses problem , since there I feel she is repeatedly since this is done several hours
I do not know what * .XML involved or whether if it is rejected by the server
where I can see this error ?
is there a way to save * .LOG for that landmark error?
next 5.2.1 will fix this problem?
