Adobe Flash Player download wont work.

I have a custom desktop PC which is running Win XP SP3 OS. It also has Google Chrome, IE8 and Firefox V5 as browsers and all have been working without any problem. I recently downloaded the latest versiou of Chrome...12 or 13 which was just released early last week...the upgrade is working fine, but apparently  as a result of downloading this upgrade i started receiving messeages saying i need to download Adobe Flash Player. Sooo...i did download FP version 10.3.181.34...this is the version of IE and Firefox. I went through all the usual download screens and got the message saying it had been downloaded successfully. I checked my Add/Rem listing and it is listed there as properly installed and working. Unfortunately, every time i use a program which requires the FP i get the same message that i need to download Adobe FP.  I have gone through all of my system settings ...Security etc. The Flash Player icon in my Control Panel shows the FP as properly installed. I run AVG anti virus software so i turned all of that off and tried to open a website which required FP and still no success. My PC is working properly and running smoothly in all other respects and I have never had a problem with any Adobe product before. I have run Advanced System Care...deep scan which i usually do bi weekly...no help. I have checked all of my security settings and set them all on low ...no help. I am not a computer technician and have sort of run out of options. As probably an important aside...at the same time as my problem with the FP started I also received an Error message...:0x8007043B...following up on that via Microsoft it said that BITS is not running and outlined several steps to take to resolve that problem..I followed them to the letter several times but they didnt solve the problem.BITS is still not running and while i have no idea what that is I'm sure it is either the or one of the reasons I am unable to get FP to work even though it is downloaded properly.

Im sure I have left out some important information,but will be happy to provide it if anyone can take the time to help me solve this problem. I even tried to identify the previous version of Chrome so I could delete the recent upgrade and resinstall it and cant find it anywhere! Finally, I tried to solve my problem using System Restore going back to before I downloaded the newest version of Chrome...no luck there either.

Thanks very much for any help .
