Wallet Error?

My apologies, still really new to this so not sure how to solve this issue, or whether it's really an issue at all.

I started out trying to use Armory as my client and using bitcoind. Apparently I had an error with my bitcoind and had to delete the .blk file it had formed as it had made an error. Using the faucets from the topic listing free bitcoins, I had them sent to my wallet I made in Armory three days ago and still haven't received them, while the account I made after a bit at MtGox has gotten plenty since then.

Trying to see if it was my Armory client messing up and seeing if they did make it to the wallet I exported the wallet information and switched to Multibit and tried to import it. When I did I got this error message:

"com.google.protobuf.InvalidProtocolBufferException Protocol message contained an invalid tag (zero)."

Not quite sure what that means. Is the wallet invalid for some reason or other, or are the two clients not compatible or something else all together?

Thanks for any answers in advance.
