Okay, I have some new information. The error occurs only if i open the spreadsheet in Google Docs and then close the tab. Everything works fine if i keep the spreadsheet tab open in the background.
When i try reading data after closing the spreadsheet tab i get the internal server error. This then "locks" the spreadsheet for a few minutes - all subsequent attempts to read the data fail. Trying to open the spreadsheet in Google Docs directly results in the error below. Is there maybe some kind of caching going on that my attempt to read the data messes with? Google Docs Error: *We're sorry.* We're sorry, a server error occurred. Please wait a bit and try reloading your spreadsheet. Find out more at the Google Docs Help Center<http://docs.google.com/support/bin/topic.py?topic=15115&hl=en> . Here is the code i use to read the data: *AtomLink worksheetLink = entry.Links.FindService (GDataSpreadsheetsNameTable.WorksheetRel, null); WorksheetQuery worksheetQuery = new WorksheetQuery (worksheetLink.HRef.ToString ()); WorksheetFeed worksheetFeed = googleServices.SpreadsheetsService.Query (worksheetQuery); // exception here WorksheetEntry worksheetEntry = (WorksheetEntry)worksheetFeed.Entries[0]; AtomLink listFeedLink = worksheetEntry.Links.FindService (GDataSpreadsheetsNameTable.ListRel, null); ListQuery listQuery = new ListQuery (listFeedLink.HRef.ToString ()); ListFeed listFeed = googleServices.SpreadsheetsService.Query (listQuery);* Martin
