I try to upgrade my RMX 2000 from version 6.02.11 to 7.03. I alaways got an error on the install mode. This message is "download version failed". I try install the update directly on port 3 of the RMX i got the same error message. My MPM cars is a MPM-H. Do you have any idea about this problem ?

error message for the file is missing in the patch,download patch once more time and then try agin
