Just wondering , that looks like syntax error. Have you modified any of the code in the events. 

Seems like a classic case of missing semi-colons or brackets.

Would really need to see the code to be able to tell you anything definitive.

Thanks...checking for the syntax... its just a workflow project, so i have asked my client to check their cstomized code.

Hi,

The warning error message, this is common messsage. The other error messages are related to C# Syntax. Maybe, you can start looking at the codes behind server event(s).
