InfoPath Dev

We have added custom code VB code to a button in InfoPath.  We were able to go through all the steps of having a Code Signing Certificate, uploading the template to the site collection. We are able to view the form just fine.  When we press the button to run the code this error comes up.

 Have you checked your SharePoint trace logs for the correlation ID? You'll find more information on what has gone wrong there, I imagine...

We can't view our log files are know where the are at.  I've tried to locate them on %CommonProgramFiles%\Microsoft Shared\Web Server Extensions\14\LOGS\.

Is there a location in the server that I'm not looking at?  Thanks Hilary

 You'll have to go into Central Admin and find out where they are. http://technet.microsoft.com/en-us/library/ee748619(v=office.14).aspx

It had something to do with the vb code writing to a text file. 

 Did you find the actual error message in the trace log? The error message may help you figure out the issue with your code. Or help me help you.

Couldn't find the log file.  but we ran the vb code withou the text file write and it worked.  I looked in both servers for the logs.  Thanks

Default location for SharePoint 2010 is c:\Program Files\Common Files\Microsoft Shared\web server extensions\14\LOGS
