Heya pls help me with this problem.

was using 0.38.1 and it has worked awesomely so far. today i had problems with it, and i've tried to reinstall but it just doesnt launch. you can see in windows task manager the process to start but it ends in 5 secs without anything else happening. i've tried to delete all the old folders and do a "clean install" but still doesn't launch. 39.0 and above launches but seems to initialize a long time. are there other folders to delete beside the appdata/roaming folder and monero client folder? seems like the new install remembers the old paths of the client i had before, how is that possible? if i try to use the backup manager with 39.0 while initializing it crashes the client, tho not a massive surprise.  or what to do
