I has a similar problem, but more severe. I searched blizz forums from top to bottom, googled, and even Mapster did not even have a solution.This is the closest I could get...
The problem is that sc2 1.5.2 crashes to desktop, just right after showing the gold/yellow "Streaming..." progress bar close to the bnet rotating logo, when creating private/joining a match.
It through's the error reporter with a [ACCESS_VIOLATION (0xC0000005) (occurred at 0023:00801381. The memory at '0x00000254' could not be read.) ] . Before everyone blames RAM for the error, as it normally is a ram issue, it only happens with 1 custom map. And this is the point of this post.
It is a custom map I uploaded a while ago and worked in 1.5.1. Since the 1.5.2 update I decided to add the arcade info with some screenshots and stuff, this is where everything went weird. To ICEMASTER, your comment on you not being able to correct the lobby issue by re-uploading an earliier working version is a view I share. It seems that even after removing it from bnet with the download/upload manager and uploading the previous version again I had saved (luckily). It still appears to be the same version, with the same issue. And editor test works, but lobby create fails....
Even stranger is that I asked other sc players to create a lobby, AND THEY COULD.... WTF ?
When I delve into the gamelogs and find the crash .txt files I see in .... crash streaming.txt that a few lines read [72,129,480ms ID:00000000 Pr:00000000 18,446,744,073,709,551,615 + 0 RequestFile() - File doesn't exist "" ""] and I believe this is what the sc exe cannot 'read' with the C000005 exception.
Does this mean I might have a currupt cache / update? There is no custom data / units in the map and uses all standard dependencies. Team setup is minimal and only has 1 variant setup.
This is sooooooo frustrating as I cannot test the map properly online. Allready checked memtest, disk, win updates, gfx drivers, temps etc. All good. Posting the logs is useless except what I could see as useful.
ANY HELP / SOLUTION is very welcome...
[UPDATE] I narrowed it down to 2 things,by adding the challenges dependancy.When I opened the data editor I saw trigger error popup in debug mode when I tested: 1. Terratron STAND was missing 2. a few talking portrait cinematic was missing(the action was defaulted to Unknown Function in triggers)
I think my 1.5.2 update didn't properly download. Pity Blizz removed the manual repairtool.
