hi

how to upgrade my wallet from Version 0.8.8.1 to Version 0.8.8.6 ??

now, when I open 0.8.8.6 simplewallet, its auto closed....

There's a bug with the 0.8.8.6 wallet converter that's fixed in 0.8.8.7 (not tagged yet) - are you able to compile the latest version from Github? Alternatively, you can use 0.8.8.6 and restore from your mnemonic seed, or failing that I can see if I can give you a more recent build of simplewallet for your OS.

bitmonero wallet v0.8.8.6-release
Specify wallet file name (e.g., wallet.bin). If the wallet doesn't exist, it wil
l be created.
Wallet file name: mro
password: *****
Error: failed to load wallet: failed to read file "mro"

wallet.bin cant working, what can I do ?

my system is win 2k11

You quoted the solution from fluffypony in your response. You can't use 0.8.8.6 to update old wallets. Look what version you're using.

You can build from source following the instructions here: https://github.com/monero-project/bitmonero
Or you can restore from your mnemonic seed if you have one.
Or you can ask fluffypony to send you a newer 0.8.8.7 version build of simplewallet.

Also, not sure what win 2k11 is...

win 2k11 is windows operatoin system server2011 64bit version
