MapThis!, 6.60 B9, psp-290 problems. Give me a hand?

Hello.

I have recently installed MapThis 5.20. When downloading I read that it would contain 2 versions of the program 1 for psp-290 and one for other recievers. The rar I got only contained 1 E-boot. I am using a psp-290

It can run and veiw maps that I have made, however when I press start it brings up a window with no contents in. Also I cannot seem to get any signal, it is always 6 empty red bars, I have redownloaded everything and I get the same problem.

I am running 6.60 pro B9 on a FAT psp-1003, and using a psp-290.

I'd love some help with this if someone has some time.
Thanks,
Chris.
