Hi,
I just downloaded the latest version for Windows 64bit (v0.8.8.2) and pasted it over my older v0.8.5 install.
I left everything else in the folder, including my wallet.bin and wallet.bin.keys files (which I called "mein_wallet.bin" and "mein_wallet.bin.keys").
After starting bitmonerod.exe it synchronizes with the network for some time till it tells me that it is synchronized and I can start up simplewallet.exe
When I do, it synchronizes as well until it reaches the last block and shuts itself down with out warning. Restarting simplewallet.exe yields the same result.
This is the simplewallet.log print out:

Ok, I made some progress: In order to start up simplewallet.exe I made a shortcut of it, already containing the parameters like "--wallet-file=mein_wallet.bin", etc. I forgot to change the path in the shortcut's target field to the correct install directory of Monero, so it was looking for the .keys file in the wrong folder all the time (the folder where I unzipped the update in originally). Now the .keys file is found correctly and my account can be accessed but only for the fraction of a second after starting up simplewallet.exe because it shuts itself down right after catching up to the blockchain and I cant do anything there. The simplewallet.log reads:
