Hi,

Thank you for your API.

I have built a system that allows user to collaborate on Word, Excel and PowerPoint documentation and this is generally working well. 

I have an issue now that when I try to open Excel documents, I get back the url for the first attempt to open, I when I try to get a second url for the other user I get the following error:

RESULT=FALSE

ERROR_CODE=2502

WARNING=Internal Server Error while processing this request

Today is the first day that I have received this particular error

Thanks
