ASA Error: Invalid DOS media or no media in slot

About a week back I used the erase command but actually (I think) erased my .bin image file from one of my ASA 5520s (We were in Active/Active configuration during testing, but decided to go with Active/Passive) so I attempted to erase the configuration but I used the wrong command. After the ASA booted straight into ROMMON because it said there was no boot image. I took the .bin file from my still working ASA tftpd it onto a server... loaded it onto the "Broken" ASA and it booted back into the ciscoasa> prompt, which was of course a good thing. Only problem is that now it says "Invalid DOS media or no media in slot" when I try to access disk0:, do a dir or save my running-config to my startup-config.

On a side note.... I am also getting this error when I try to enter my new activation key (and are these 2 things related.... ie. do I need the key to access Disk0:?)

ciscoasa# activation-key 0xe913324r 0xe4a42936 0x54e13828 0xc238c0d4 0xc55cg8547 (Made up numbers)

Failed to update the flash activation key

ERROR: Failed to update flash activation key

Any help regarding either issue would be greatly appreciated.

Thanks in advance,

Chris

Just wanted to bump this back up the queue a little bit so people would be able to see it better... I figure someone out there has to know a fix

Thanks,
