Bitcoin-qt Issue

[marks1976]

Upon upgrading to bitcoin-qt 0.6.2 I am receiving a Visual C++ runtime error. I am using windows 7. I tried reinstall and still no luck.  I deleted all files except wallet.dat in the folder.  Once I started bitcoin client again gets started and fails syncing the blockchain at block#168514.  This problem is something new since it was running up until yesterday.  Prior to that no problem.

fails syncing the blockchain at block#168514.

What do you mean by "fails"? It's not unusual for it to stop and wait until the next block on the network is found during syncup.

The reason you were unable to start until you deleted your database is probably because your software was not cleanly shutdown before upgrading.

Fails due to the fact of the C++ Runtime error.  168514 is not the most recent block.  The bitcoin client only gets to block 168514 before the runtime error. It updates only until about 80 days ago.  Block chain loads fine until that point.

Did you really delete _all_ the files except the wallet.dat, including the database directory and _db.000 files?

I removed the files yes I have them still backed up.  I tried clean install of bitcoin 0.6.2 and loads everything back to the same spot.  I can put those files back but was giving me the error when the files were there.

Do you have a bitcoin.conf or start with any special arguments like telling it to connect to a single particular node or use a proxy?  How many connections do you have when the node is running? Are you running low on disk space?

Windows 7 machinewith no special arguments.  I start bitcoin-qt and says it loads all info.  Then when it loads it makes 12 connections last time and when it tries to get the rest of block info C++ Runtime error.

Can you paste the text of the runtime error along with the last dozen or so lines from your debug.log file?

Microsoft Visual C++ Runtime Library.

This application has requested the Runtime to terminate it in an unusual way.

When you deleted everything did you also delete addr.dat?  If not then I suspect you have a failing disk.

[marks1976]

Yes I did delete addr.dat.  I tried to restore it with no luck.

Things you could try:
see if the daemon version is crashing too
run a memory test
run a hard disk test

I'd recommend all of these.
But also just to be sure, you should backup your wallet and see if bitcoin runs fine with a blank wallet.
If it does, your wallet could be corrupt and might need fixed.
