Fatal error: Cannot redeclare class vmRequest

[CyComodo]

Hi!

I upgraded Virtuemart 1.5.4 to 2.0.2 by installing com_virtuemart.2.0.2 and com_virtuemart.2.0.2_ext_aio folders.
Download was successful. But when I tried to open Virtuemart in administrator components menu then first time it showed me the 500 internal server error. Then later it showed me white page. So i turned on the error reporting and it says: Fatal error: Cannot redeclare class vmRequest in administrator/components/com_virtuemart/classes/request.class.php on line 597

I have Joomla 1.5.22

Any idea?

Thank you!

There is no VirtueMart 1.5.4 version. So what did you upgrade?
