Template error while uploading "bigger" pics (?)

[jmmc]

Hey, I was wondering if anyone can help with something on my recently installed v1.5.18.
So I'm starting this new gallery and I was uploading some files and everything seemed alright, I used the same general configs for file settings etc I had on other gallery I have for some years now but for some reason it won't let me upload the bigger files in size or just dimensions (but not that HUGE though), I dont understand if its random or not since the configs as I mentioned for the max size and width/height.
Anyway here's the error that I get along with the failed to upload on the album icon in both the most common way for me (at batch add files) as well as the simple "upload file" one:

Template errorFailed to find block 'file_line' (#<!-- BEGIN file_line -->(.*?)<!-- END file_line -->#s) in :                    <div class="{CSS_CLASS}">
                        <h2>{HEADER_TXT}</h2>
                        <span class="cpg_user_message">{MESSAGE}</span>


                        <br /><br />
                    </div>

Can anyone please help me how to fix it?

Thanks so much in advance!

Thanks for your reply, I just installed this gallery a couple days and downloaded the one that looked the most recent version of the site.
The message is still there "Looking for the latest version? Download cpg1.5.18.zip (19.0 MB)" so I downloaded that.

Anyway I tried that already, changed to "eyeball" and "hardwired" (I'm using "curve") and had the same problem in all of them
