Android market apps download unsuccessful, please try later solve

HI, Android users, I'm using wildfire s OS.v- 2.3.5. When I bought the phone my android market was running successful, I could download all my apps successfully from the market. Never thought that i will be facing problem like, unable to download apps from the market. When i try to download any software from the market its shows DOWNLOAD UNSUCCESSFUL, PLEASE TRY LATER, I was worried, if I could'not download any software from the market how can I have the latest updates and have all other application in my Android phone. Than I research on the Internet and found nothing to solve my problem. So I decided to try myself and solve the problem. *

Here are the following try i have made.


* I try to restart the phone and remove the battery along with the sim card and waited for 2-3 minute. Than I power on the phone.
Result: Not solve

* Then I try to go to MENU--->SETTING--->APPLICATION--->MANAGE APPLICATION--->ALL--->MARKET and MARKET FEEDBACK AGENT. First I have click CLEAR CACHE from MARKET FEEDBACK AGENT and FORCE CLOSE. And than went to MARKET and I have did what I have done in MARKET FEEDBACK AGENT too.
( I also had updated all the apps which are available to update even though it cant be download, it removes the update option. I did this because I think it may be the reason too )
Result: Solve

* MY Android version is 2.3.5
* MY market version is 2.3.4 and MARKET FEEDBACK AGENT version is 2.3.3.
* The force close option may not be clickable in MARKET FEEDBACK AGENT. (No problem with it)
