The error has been fixed!
I noticed that the new version (2.1) of the mod was causing crashes, so I searched for the problem and I found it. Now it's allright, it works.
V2.1 is now available!
Now you can download the new version of the mod!
Note: I was updating the files, when I accidentally deleted the TaxiMod Pack V1.0. If anyone has already downloaded it, he's pleased to send me the file via PM. Thank you.
