Can't start up Plants vs Zombies

I keep getting this error when ever I start it up. The window starts up but it is just a black screen and I get this error.

I've tried reinstalling but it doesn't help :S. I'm running an Acer Aspire 5920 laptop and Vista and all my other games work.

It looks like the game is loading the wrong version of bass.dll. Maybe a different version of bass.dll is in your path?

Did anyone find a solution to this? There seems to be a lot of talk about Asus Xonar soundcards, but I am getting this error and have an X-Fi.

Currently awaiting some kind of reply from both Popcap and Valve.

Anyone any ideas?


P.S. I've reinstalled both Steam and PvZ and run Steam as an administrator, but not change.

Problem resolved for me.

For those without Xenor cards, this error can still occur. It's actually nothing to do with the soundcard in this case, but an incorrectly directed base.dll file.

To resolve this, search your system for base.dll and identify multiple copies. The file is inherantly the same save the version. Once you locate duplicate base.dll files, copy-replace the popcap version over the others. Your game should now load.

In short, if you have this problem without a Xonar card, it is because your system is using another version of the base.dll file instead of the popcap one. Replacing the incorrect base.dll files will let your game run without compromising other files.

For the record, I found two on my system under:

C:\Program Files\Vista Codec Pack.

I suggest you check one or both dirs first.

I already found the solution, all you have to do is change the PvrZ compatability mode thing to xp and it seems to work.

I'm getting the same error.
Synboi, How do you change the PvrZ compatibility mode thing to xp?
Never-mind I deleted the bass.dll from the system32, works great now.
