Have seed, have password, have wallet file, but can't load it in Electrum!

I don't have access to the Windows machine right now, but that wallet should still be on the Windows machine. However, I want to load it on my Linux machine. I copied my wallet file from Electrum on Windows and am trying to open it in Electrum on Linux. It is about 8k in size, is a plain text file and has fields like this:

   "accounts": {
   "0": {
   "change": [

"receiving": [

   "accounts_expanded": {},
   "addr_history": {

   "master_private_keys": {
   "master_public_keys": {

   "pruned_txo": {},
   "seed":
   "use_encryption": true,
   "wallet_type": "standard",
   "winpos-qt": [

That is not all of them, and I left off the included data. I just wanted to give an example of the type of file I have.

But everything with that file seems to be in order. However, if I copy it to my wallets directory and try to load it directly by typing 'electrum -w ~/.electrum/wallets/new_wallet' I get:

File "/usr/lib/python2.7/dist-packages/electrum/wallet.py", line 121, in read
   raise IOError("Cannot read wallet file.")
IOError: Cannot read wallet file.

If I load Electrum and do New/Restore, and paste in my 12-word seed, I get "Incorrect seed". I am sure that the seed is correct. I copied and pasted the seed directly into a text file specifically for transferring from Windows to Linux.

Besides going back to the Windows machine (Which I don't have access to right now), what else can I try?

It's not a problem of carriage-returns in the wallet file, is it? (because it was from a Windows machine and now I am on Linux). If so, how do I fix that?

Is the file I mentioned at the beginning of this post the actual wallet file? Or am I missing some other file? If I create a brand new wallet in Electrum it has similar fields, although not all of the ones in my file.
