Unable to sign in to admin

After installing your script, which was not as easy as some cart scripts I've come across, I finally got the code working and began setting up my shopping cart, after a while i returned to the page to find I was completely unable to sign into any of the account including admin.

I removed the script completely and started again from scratch, only to find that after installing... IT WOULD NOT SIGN IN

After banging my head against the nearest brick wall for some hours, I went in search for a more reliable shopping cart package, I found one in minutes that had included a very speedy installer that made installation extremely simple and automated.

Your script would be brilliant first if only you could creat a simple installer, and was more predictable in performance.

I was desperate to get a shopping cart installed and was on a deadline to resolve the issue, being unable to post here for some while didn't make things any easier.

Suggestion: when installing the SQL database entries, you should have a script that allows the user to define a prefix for the database entries, as a number of your entries overwrote files in my existing database. NOT GOOD!

If you can resolve these issues I would be willing to invest in your shopping script again.
It was good for the short while that it worked, but way too much of a headache otherwise.

I have subscribed to this thread in the hope you can help.

Thanks in advance...
