voobly crashes multiple times. as soon as the aoc application starts the whole voobly collapses to nothing and I have to relogin. happened more than 10 times in 3 days

Please paste us the result of the game diagnostics. Also make sure you are using the recommended game room settings:

Regarding the crashing issue: next time the client is crashing for you, FIRST upload the voobly.txt in your Voobly Client Installation folder BEFORE logging onto Voobly again. Thank you.
