If it's password protected you have to use Multidoge.
However, I am at the computer now and I can provide some steps.
!!! Make sure you do this on a clean computer. If you have some malware that gives out your private keys to 3rd party,, your doecoin will be lost forever. !!!
First of all, please make sure you made a backup of doges.wallet somewhere. Another partition, or an USB stick are the first options.
Then open Multidoge and make sure you have doges.wallet opened. If it's not, make an extra copy, let's say d:\test_doge\doges.wallet, go to Multidoge, File->Open Wallet->select d:\test_doge\doges.wallet
Open Tools->Export private keys and then in the list of wallets at the left make sure the correct wallet is selected. In the right area you'll see the path to the wallet file.
Type the wallet password.
In the section "Export file" make sure the path is OK for you and you remember it.
Then select "Do not password protect" and click "export private keys". (we need them clearly visible for importing into dogecoin core)
Make a copy of the resulted doges.key. Let's call it doges2.key
Open the resulted doges.key with Notepad (open notepad and drag doges.key into it).
There are plenty of rows that start with # and those don't matter, you can delete them.
At least one row will start with some long strange string of characters, then a space and a strange looking date.
That space and date you can also delete.
It'll remain only that strange long string. That's the private key which can be also imported into dogecoin core. Please save the file (you can overwrite doges.key).
I'll start with Importing into Multidoge.
File->New wallet.
Tools->Import private keys
At Import File click Import From and find doges2.key
Click Import private keys. Then wait patiently for the new wallet to synchronize.
If all the steps went well and you still cannot send out dogecoins, please keep doges.key and I'll make you the steps to import the key into dogecoin core.
!!! Please store your private keys safe, anyone that has them can spend your dogecoin. !!!
Edit:
Since I don't have Dogecoin to see Multidoge is still working at sending transactions (mine also shows disabled Send, but with 0 Doge it's normal), I'll be continuing with Dogecoin core.
Obviously download it from https://dogecoin.com/ , install it, start it.
Open doges.key into Notepad, copy the_long_strange_string, go back to Dogecoin core.
Help->Debug window. Go to the tab called Console and type + paste:
importprivkey the_long_strange_string
And press enter.
For a test go to File->Much receiving addresses, you should see your address in the list.
And wait. A lot. Probably days. Dogecoin core has to synchronize. It will use CPU, bandwidth and disk space.
On the bottom it shows how old are the blocks last synchronized.
When it's sync-ed, you should be able to spend your coins.
Hey wow thanks for the long reply lol, but when i open it in the wallet the export private key button is greyed out and wont let me click. Im going to try it on multiple computers but well see
