Error opening file in a package

Question

I just finished a translation from a package. One of the files was translated, but now when I reopen the file to review it I receive 2 messages: "An exception was thrown by the target of an invocation," and "Index (zero based) must be greater than or equal to zero and less than the size of the argument list." This is very new to me (problem never encountered before) and I wish I understood what this means and how to remedy it.

Hi Nelly, 
 
You don't mention what version of Studio, which sometimes helps. In this case however it may be that you have some Anti-Virus, security or clean up utility that has wiped the temp files Studio was using for the translation. 
 
So if you have saved your work to a TM as you worked try removing the project from Studio (then in windows explorer zip it up, save it safely and delete the project files), open the package again and pretranslate from your TM to get back to where you were.
