Blowfish encryption oddity

[Yumblie]

So my program has a bunch of text files that are stored externally, and I'd like to have them encrypted. I have a "save" event that seems to encrypt them all just fine. But when the "load" event occurs to decrypt them, it only seems to decrypt every other file. I gave them all different keys, and no matter what I do, the same files are decrypted while the same ones are gibberish. From what I can see, all the files are being modified, so it looks like the gibberish files are simply being decrypted the wrong way, or something.

What's going on?

Why are you encrypting each lot of text with a different key that seems inefficient.
Change the method.
Save each text files to a separate bank using the binary object then run a 2 or 3 encryption pass if you want good security. The encryption method is similar to Tripple des (3des). You encrypt the file with key 1 then decrypt with key 2 then re encrypt with key 3.
