EasyPopulate will not work

zc ver : 1.3.9h

php version : 5.2.10

ez pop ver : 1.2.5.5 csv

We have moved to a dedicated server. Our store seems to function normally except we cannot get any version of easypopulate to accept files, (tab delineated txt or tab delineated csv.) error messages from different versions of ezpop have all been similar to this one from cache which reads:

[<a href='function.fopen'>function.fopen</a>]: failed to open stream: No such file or directory in /home/user/public_html/store/admin/easypopulate.php on line 1255
[05-May-2011 00:23:21] PHP Warning: fgetcsv() expects parameter 1 to be resource, boolean given in /home/user/public_html/store/admin/easypopulate.php on line 1256
[05-May-2011 00:23:21] PHP Warning: array_flip() [<a href='function.array-flip'>function.array-flip</a>]: The argument should be an array in /home/user/public_html/store/admin/easypopulate.php on line 1256

Please help, we are finished and ready to open but we need ezpop to be able to update prices on thousands of products.

Thanks in advance.

also, Here is a debug file while using ezpop 1.2.5.4
this appeared after uploading a tab deliminated txt file:

[29-Apr-2011 03:11:05] PHP Warning: file(/home/user/public_html/store/temp/test.txt) [<a href='function.file'>function.file</a>]: failed to open stream: No such file or directory in /home/user/public_html/store/admin/easypopulate.php on line 1179
[29-Apr-2011 03:11:05] PHP Warning: Invalid argument supplied for foreach() in /home/user/public_html/store/admin/easypopulate.php on line 1279

Hoping this sheds light on the issue.

I've looked everywhere, I've tried everything. it even happened on a clean install of ZC.
