Description of the problem:
Every time I try to download the update 1.0.12 for direwolf20 1.6.4 or any other server for that matter I continue to get: Problem with new md5 method, downloading from backup or something to that effect. Not only that but it keeps saying end of server file... very very aggravating...


Update: Seems to be an issue with the new GeoDNS, should be fixed shortly.

Update 2: GeoDNS issues should be fixed, during the GeoDNS issues there was a possibility for antivirus to flag it as malicious, however, that was a false positive and you shouldn't see it flagged again in the future as it was purely related to the DNS issue.

Hello everyone, quick announcement from me about the most recent launcher update.

For starters if you want a change-log then feel free to check it out over here.

Now onto some detailed information regarding the main changes and some additional changes to the repository.

So one of the main issues we had with our repository was the generation and caching of md5's server side.* These issues would cause updates to take 8+ hours almost every time we push an update for anything. The reasons for these issues were because the repository was not setup to handle md5s originally, it was added on top of it. To fix this issues Paul and the great people over at Creeper Host spent quite a bit of time changing up the the repository back end and mainly the generation and retrieval of md5s. However, due to all the changes I had to rewrite a fair bit of the download code on the launcher side to support the changes.

Now besides this greatly reducing the possibility for md5 issues this also should help improve performance server side quite a lot. We are making these changes and improvements now so we can test and fix up any issues if they occur now so that when the new launcher (v2.0) comes out everything works smoothly.

As another note we're rolling the changes out incrementally as to provide everyone ample time to swap over to the newest version of the launcher and to reduce issues if something was to fail on the current md5 method. Due to this we've essentially split the servers in half currently and will be slowly transferring the remaining servers onto the new method and back-end once we feel we've given users ample time to update and the new system is proven to be stable. A side effect of this might be slower downloads due to our servers being split, but as we update the other servers you should get your normal speeds again. Another possible issue with the servers available being changed is if you had a specific download server selected under the advanced options of your launcher then it would be a good idea to check your options after the update to be sure you have the correct server selected (Unseen side-effect, I apologize for the inconvenience this might bring to some).

I hope everyone enjoys the modpacks and hopefully nothing breaks ;)

*(MD5's are used to verify the integrity of files/downloads between the launcher and the repository.)
