I am recieveing the same exception when I attempt to open and load one of our project files.
The problem occured when I attempted to remotley connect to the machine running ANTS Load unaware that another user currently had the project file open. Now every time I attmept to LOAD the project it hangs for two seconds before throwing this exception
I have spoken with Ants Load tech support who I am still waiting to hear back from. I have tried rebooting the machine but at this point after reading previous posts it seems that the project file has become corupted.
If anyone has this issue resolved please let me know
If Ants support provides a solution I will post it as I can imagine I am not the first person to experience this issue.
