Is this htaccess OK?

webhosts saying there's a problem!

[lee_sufc]

I have a problem on my site and my webhosts are blaming my htaccess file. However, I am fairly sure there is nothing wrong with it.

Is it possible for an expert here to check the following:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com [NC]
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
#
##################################################### 
# FORUM 
RewriteRule ^forum/forum([0-9]+)\.html$ /forum/viewforum.php?f=$1 [QSA,L] 
# TOPIC 
RewriteRule ^forum/topic([0-9]+)\.html$ /forum/viewtopic.php?t=$1 [QSA,L] 
#####################################################

Redirect 301 /Contact_Us.htm http://www.example.com/Contact_Us.php
Redirect 301 /Links2.htm http://www.example.com/Links.htm
Redirect 301 /Links3.htm http://www.example.com/Links.htm
Redirect 301 /worldwide_resources.htm http://www.example.com/Links.htm
Redirect 301 /Linktous.htm http://www.example.com/Links.htm
Redirect 301 /Why_choose_us.htm http://www.example.com/about.htm

What kind of problem? Knowing this might help focus the examination of your code. It looks OK to me, but I don't know what kind of problem I might be looking for!

Some things here.

I would not mix directives from different modules. To do so means you cannot guarantee which order the rules will be processed.

I would avoid mixed case URLs and I never use an underscore in a URL.

Your existing code may lead to a redirection chain for some of the URLs you list.
Trace what happens when you request example.com/Contact_Us.htm for example.

Finally, you don't need to change some URLs from .htm to .php. You can either use a rewrite (not a redirect) to connect the .htm URL to the equivalent .php file on the server, or you can force .htm files to be parsed for PHP scripting.
