MSP430 CPU core in VHDL

When i tried to open test file, an error screen poped up. The text in the screen is below;

"The project file 'test.ewp' is in an old format. Would you like to convert it for use with this version? ..." I clicked "Yes", then another screen poped up; "Failed to create backup file, the file has been left untouched!" and after that i clicked "Ok", and then again an screen poped up and the text; project could not opened. I tried to solve it, there are some ways to handle this problem it according to IAR site, but it did not work for me. Here is the link; http://processors.wiki.ti.com/index.php/IAR_Project_Open_Error

If you can upload test files for newer version of IAR, it would be nice.

Thank you!
